Instruction:
Optimize a code written in C++ in order to increase its performance.
#include <iostream>
using namespace std;

// Function to calculate the sum
int sum(int arr[], int N)
{
    int result = 0;

    // Add all elements one by one
    for (int i = 0; i < N; i++)
        result += arr[i];

    return result;
}

int main()
{
	// Array of elements
	int arr[] = {1, 2, 3};
	int n = 3;

	// Function call
	int result = sum(arr, n);

	cout << "The Sum of the array is: " << result << endl;

	return 0;
}

Output:
The given C++ code can already be considered optimized as it implements a straightforward summation of elements in an array. However, to squeeze out a little more performance, you may take advantage of some minor modifications: reducing the scope of variables, avoiding unnecessary memory allocations, and using `std::accumulate`.

```cpp
#include <iostream>
#include <numeric>
using namespace std;

int main()
{
    // Array of elements
    int arr[] = {1, 2, 3};

    // Calculate the sum
    int result = std::accumulate(arr, arr+3, 0);

    cout << "The Sum of the array is: " << result << endl;

    return 0;
}
```
Here, we eliminated the function `sum()` to reduce function call overhead. Note that `std::accumulate` from STL is used for direct computations of sum.

Please note, these changes might not improve performance considerably for this specific small program, but these practices could prove beneficial in larger, more complex programs.


Instruction: Formulate a SQL directive that concurrently instigates the creation of a fresh table, specifically designated as "users", and incorporates a prototypical user entry into it, guaranteeing the directive is architectured to execute both operations in unison.

Output:
Creating a new table and inserting a prototype entry cannot be executed in one "atomic" SQL statement. SQL commands need to be executed in order. However, we can script these two operations together as given below:

```sql
BEGIN TRANSACTION;

CREATE TABLE users
(
    id INT PRIMARY KEY,
    name VARCHAR(100),
    email VARCHAR(100)
);

INSERT INTO users
VALUES (1, 'Prototype User', 'prototype@example.com');

COMMIT;
```

This script starts a transaction (if your SQL database supports this - for example in SQL Server, PostgreSQL or with `BEGIN;` in MySQL), makes the desired changes and then commits the changes to finish the transaction. This makes these changes appear to occur at the same time from the perspective of other connections.

Just note that some SQL implementations, such as SQLite or MySQL with the MyISAM storage engine, do not support transactions. In this case, the `BEGIN TRANSACTION;` and `COMMIT;` commands should be removed. Any error during the execution of this script, however, would leave the database in an inconsistent state.


Instruction:
Formulate an SQL query that not only retrieves the entire list of employees working specifically within the "Marketing" department of a company, but also calculates and ranks their total sales for the past fiscal year. Additionally, provide a comparison of their sales performance to the overall company average. You want to see who are the top-performing employees and how they compare to the company-wide average. For this problem, assume that the relevant information is spread across three tables: 'employees', 'orders', and 'sales', where:

- 'employees' contains: employee_id (primary key), name, department
- 'orders' contains: order_id (primary key), employee_id (foreign key), product_id
- 'sales' contains: sale_id (primary key), order_id (foreign key), sale_date, sale_amount

As an additional level of complexity, filter out all sales that occurred outside of the last fiscal year, which is defined from April of previous year to March of the current year. Assume that the current date is October 4, 2023.

Output:
Here's a possible SQL query to solve the problem. This query firstly aggregates total sales per employee for the last fiscal year. Next, it calculates overall average sales. The final portion of the query is providing the desired output: employee name, total sales, and comparison to the overall average.

```sql
WITH EmployeeSales AS (
    SELECT
        e.employee_id,
        e.name,
        SUM(s.sale_amount) AS TotalSales
    FROM
        employees e
    INNER JOIN
        orders o ON e.employee_id = o.employee_id
    INNER JOIN
        sales s ON o.order_id = s.order_id
    WHERE
         e.department = 'Marketing' AND
         s.sale_date BETWEEN '2022-04-01' AND '2023-03-31'  -- last fiscal year
    GROUP BY
        e.employee_id,
        e.name
),
AvgSales AS (
    SELECT
        AVG(TotalSales) AS CompanySalesAvg
    FROM
        EmployeeSales
)
SELECT
    ES.name,
    ES.TotalSales,
    ES.TotalSales - AS.CompanySalesAvg AS PerformanceComparedToAverage
FROM
    EmployeeSales ES, AvgSales AS
ORDER BY
    ES.TotalSales DESC
```

Please replace the dates `2022-04-01` and `2023-03-31` with variables or SQL function, if you want the query to dynamically define the fiscal year based on the date of execution.

Also note, this query will run assuming your RDBMS supports multiple-table select queries and CROSS JOINs behave as expected - i.e., every row from first table is combined with every row from second table. If you encounter issues, it may be necessary to adjust based on your specific environment or schema. For example, in Oracle SQL, we would need to use the dual table with AvgSales.


Instruction: Fabricate a JavaScript object that integrates parameters symbolizing distinct personages' appellation linked to their respective chronological maturity. By "chronological maturity", interpret it as their explicit ages calculated in years.

Output:
You can create a JavaScript object to solve your problem like this:

```javascript
const personages = {
    'John': 30,
    'Jane': 28,
    'Tom': 35,
    'Alice': 22
};

```

In this JavaScript object, keys ('John', 'Jane', 'Tom', 'Alice') represent different personage's names (appellation) and values (30, 28, 35, 22) represent their respective ages (chronological maturity).

You can access their ages by their names like `personages['John']` or `personages.John`, which will output `30`.


Instruction:
Implement a Java method that converts a given string to a list of strings, where each element of the list is a non-overlapping continuous substring of the given string. However, instead of using default character-by-character separation, the method should take another string parameter called "delimiter" that determines where to split the input string. The resulting list must not contain the delimiter string as an element. Additionally, the method should be able to handle multiple consecutive delimiters by treating them as a single delimiter.

For example:

Input: `inputString = "abc||def||ghi||jkl||mno", delimiter = "||"`
Output: `["abc", "def", "ghi", "jkl", "mno"]`

Input: `inputString = "aaa--b-c--d--e-f", delimiter = "--"`
Output: `["aaa", "b-c", "d", "e-f"]`

Function signature: `public List<String> convertStringToList(String inputString, String delimiter)`

Output:
In this problem, Java's built-in string method `split()` may come in handy. This method splits the given string around the matches of the given delimiter, and ignores multiple consecutive delimiters. The `split()` method returns an array, so you can convert this array to a list by using `Arrays.asList()`. Here's how you can solve this problem:

```java
import java.util.Arrays;
import java.util.List;

public List<String> convertStringToList(String inputString, String delimiter) {
    // split the string around the matches of the delimiter
    String[] splitArray = inputString.split(java.util.regex.Pattern.quote(delimiter));

    // convert the array to a list and return it
    return Arrays.asList(splitArray);
}
```

You can then use this method like this:

```java
convertStringToList("abc||def||ghi||jkl||mno", "||");
// this returns ["abc", "def", "ghi", "jkl", "mno"]

convertStringToList("aaa--b-c--d--e-f", "--");
// this returns ["aaa", "b-c", "d", "e-f"]
```

Note: If the delimiter contains special regex characters (such as `.`, `|`, `*`, `+`, `?`, `{`, `}`, `[`, `]`, `\`, `^`, `$`, and `()`), they should be escaped with `\\` before passing to `split()`. But `Pattern.quote(delimiter)` here does exactly that, it returns a string that can be used to match any sequence of characters that would be equivalent to `delimiter` as if it were a literal pattern. You can use this `Pattern.quote(delimiter)` to avoid exceptions when passing special regex characters as a delimiter.


Instruction: Formulate a regular expression pattern discerning a chain of characters encapsulating both the precise lexical constituents "hello" and "world", demanding crucial understanding of pattern recognition and comprehension of string organization.

Output:
Here is the Python code snippet for a regular expression pattern that discerns a chain of characters containing both "hello" and "world":

```python
import re

def check_string(string):
    pattern = r"(?=.*hello)(?=.*world)"
    return bool(re.search(pattern, string))
```

Here, the pattern `(?=.*hello)(?=.*world)` is used to check the input string. This pattern uses positive lookaheads (`?=...`) to confirm the existence of both "hello" and "world" anywhere within the string, in any order.

Let's show this in action by example:

```python
print(check_string("hello there, world"))  # Should print: True
print(check_string("world, hello"))  # Should print: True
print(check_string("world"))  # Should print: False
```

The provided function `check_string(string)` will return `True` if the input string contains both "hello" and "world", and `False` otherwise. Note that it isn't case sensitive, meaning it will only match exactly "hello" and "world", not "Hello", "World", etc. If you need it to be case insensitive you can modify the pattern to `(?=.*hello)(?=.*world)` and use `re.search(pattern, string, re.IGNORECASE)` instead.


Instruction: Generate a gRPC client in Golang that can communicate with a server running on localhost:8080.

Output:
To create a gRPC client in Golang, you first need to define the service in a .proto file. However, since it's not specified in the question, we'll assume it's already defined and compiled to Golang.

Let's walk through a simple example.

First of all, you need to install the gRPC package:

```bash
$ go get -u google.golang.org/grpc
```

Then, the gRPC client can be defined the following way:

```go
package main

import (
	pb "path/to/your/protobuf/service"
	"golang.org/x/net/context"
	"google.golang.org/grpc"
	"log"
)

const (
	address     = "localhost:8080"
)

func main() {
	// Set up a connection to the server.
	conn, err := grpc.Dial(address, grpc.WithInsecure())
	if err != nil {
		log.Fatalf("did not connect: %v", err)
	}
	defer conn.Close()
	// Create new client
	c := pb.NewYourServiceClient(conn)

	// Define the context
	ctx := context.Background()

	// Call the method (replace with your method name and request)
	response, err := c.YourMethod(ctx, &pb.YourRequest{})
	if err != nil {
		log.Fatalf("could not call: %v", err)
	}

	log.Printf("Response: %v", response)
}
```

Replace "path/to/your/protobuf/service" with the path of your generated protobuf service.

Replace "YourServiceClient", "YourMethod" and "YourRequest" with corresponding entities from your protocol buffers definition.

In the address constant, 8080 is defined as the port and localhost as the address where your server is running.

You also need to ensure the server's started on expected address and port before running this client.

Remember, this is a basic example. In real-life scenarios, you would likely need to handle scenarios related to timeouts, security (TLS/SSL, JWT, OAuth) when dialing a service, error handling, etc.


Instruction:
Write a program that will perform the following operations using the given nested JSON data:

1. Extract the age of the second hobby of the first student.
2. Calculate the average hobby age of the first student.
3. Extract the hobby name which the second student has been doing for the longest.

Here is the JSON structure:

[
  {
    "studentName": "Paul",
    "studentAge": 28,
    "hobbies": [
      {
        "hobbyName": "Football",
        "hobbyAge": 5
      },
      {
        "hobbyName": "Chess",
        "hobbyAge": 2
      },
      {
        "hobbyName": "Running",
        "hobbyAge": 3
      }
    ]
  },
  {
    "studentName": "Nina",
    "studentAge": 30,
    "hobbies": [
      {
        "hobbyName": "Painting",
        "hobbyAge": 4
      },
      {
        "hobbyName": "Dancing",
        "hobbyAge": 3
      },
      {
        "hobbyName": "Cooking",
        "hobbyAge": 6
      }
    ]
  }
]

Output:
Here is a Python solution for the problem:

```python
import json

# Parse JSON data
students = json.loads('[{"studentName": "Paul","studentAge": 28,"hobbies": [{"hobbyName": "Football","hobbyAge": 5},{"hobbyName": "Chess","hobbyAge": 2},{"hobbyName": "Running","hobbyAge": 3}]},{"studentName": "Nina","studentAge": 30,"hobbies": [{"hobbyName": "Painting","hobbyAge": 4},{"hobbyName": "Dancing","hobbyAge": 3},{"hobbyName": "Cooking","hobbyAge": 6}]}]')

# 1. Extract the age of the second hobby of the first student.
second_hobby_age = students[0]['hobbies'][1]['hobbyAge']
print(f"Age of the second hobby of the first student is: {second_hobby_age}")

# 2. Calculate the average hobby age of the first student.
hobby_ages = [hobby['hobbyAge'] for hobby in students[0]['hobbies']]
average_hobby_age = sum(hobby_ages) / len(hobby_ages)
print(f"Average hobby age of the first student is: {average_hobby_age}")

# 3. Extract the hobby name which the second student has been doing for the longest.
oldest_hobby = max(students[1]['hobbies'], key=lambda hobby: hobby['hobbyAge'])
print(f"The hobby which the second student has been doing for the longest is: {oldest_hobby['hobbyName']}")
```

In this code, `students` is a list of dictionaries parsed from the provided JSON data. The program then uses list and dictionary indexing to access the requested information. For the second part, a list comprehension is used to collect all the hobby ages of the first student and the `sum` and `len` functions are used to calculate the average. For the third part, the `max` function is used with a key argument to find the hobby with the maximum age for the second student.

Output:
Giving an SVG image a hand-drawn effect is not easily accomplished directly within the SVG code itself, as making an image look hand-drawn requires irregularities, imperfect lines, and a certain organic randomness that simply aren't achievable with the straight lines and perfect curves that SVGs rely on.

However, you can achieve this effect through a few different methods outside of the SVG markup:

1. AI-Based Filters: You can use stroke-based rendering and AI-based filters to transform SVG images into something that looks hand-drawn. For example, websites such as DeepArt or apps like Adobe Fresco can help you create a hand-drawn effect.

2. Photoshop: Use Photoshop or a similar photo editing software to apply sketched effects filters on the SVG.

3. CSS Trick: You can try this cool CSS trick that suggests a hand-drawn, sketchy, rough look and feel by using multiple overlapping strokes, which are slightly displaced.

```css
  path {
    stroke: black;
    stroke-width: 1;
    stroke-dasharray: 6,2;
    stroke-linejoin: round;
    stroke-linecap: round;
  }

  path:before,
  path:after {
    content: '';
    display: block;
    position: relative;
    width: 100%;
    height: 100%;
    background: inherit;
    top: -2px;
    left: -2px;
    z-index: -1;
  }

  path:before {
    top: 1px;
    left: 1px;
  }
```
Above CSS might not give perfect hand-drawn effect. Adjust parameters accordingly.

4. Hand-Drawing Software: Use software like Illustrator and its brushes to actually hand draw the desired image or convert your existing SVG to a sketch design. Redrawing or adding manual effects is the most authentic way to get a hand-drawn look.

Remember, it is often the slight imperfection and irregularity of lines, the varying stroke width etc that gives a design a hand-drawn feel. You might have to iterate and experiment a lot regardless of which method you choose.


Instruction:
Devise an SQL query to unify two distinct data tables employing a technique known as left join.

TableFirst:
id | metropolis
1 | New York
2 | Los Angeles

TableSecond:
id | inhabitants
1 | 8,400,000
2 | 3,900,000

Output:
You can use an SQL LEFT JOIN to combine these two tables. The basic syntax for a LEFT JOIN is `table1 LEFT JOIN table2 ON table1.column = table2.column`.

Here is how you might write an SQL query to combine your two example tables:

```sql
SELECT TableFirst.id, TableFirst.metropolis, TableSecond.inhabitants
FROM TableFirst
LEFT JOIN TableSecond
ON TableFirst.id = TableSecond.id;
```

This query will return a new table that includes all the records from the TableFirst, even if there is no match in TableSecond. If there is a match in both tables, the query will return the matching records from both tables. If there is no match, the result is NULL.

Here is the resulting table:
id | metropolis | inhabitants
1 | New York | 8,400,000
2 | Los Angeles | 3,900,000

Please make sure the tables and columns you have in your query exist in your database; otherwise, you will get an error. Do replace 'TableFirst', 'TableSecond' with the real table names, and 'id', 'metropolis', 'inhabitants' with your real column names.


Instruction:
Augment the complexity of the examination question related to programming:

Elaborate on the ensuing code piece:

def custom_base_arithmetic_operations(n, m, base, operation, precision):
    """You are provided with two positive integers n and m, a singular integer termed as base varying between [2, 16] (inclusive),
    a varied String operation which could encompass one of the subsequent ["sum", "diff", "product", "average", "median", "mode"],
    and an integer precision to ascertain the decimal places to be considered for rounding off the result.

    Your mission consists of the ensuing steps:
    1. Primarily, consummate the operation mentioned with the integers within the list from n to m (inclusive).
    2. Subsequently, align the final result to the nearest integer considering the precision decimal places.
    3. Ultimately, recast that outcome into the custom base system and disseminate the final figure.

    In cases when n overshadows m, reciprocate with -1.
    If base surpasses the sanctioned limit or lies outside the accepted bracket, respond with -1.
    If precision languishes below 0 or vaults over 10, reciprocate with -1.

    Sample Illustration:
    custom_base_arithmetic_operations(1, 5, 2, "average", 2) => "0b11.01"
    custom_base_arithmetic_operations(7, 5, 2, "sum", 0) => -1
    custom_base_arithmetic_operations(20, 33, 2, "median", 1) => "0b1101.1"
    """

Devise a function that computes the custom base representation taking into account the provided parameters, actualizes the designated operation,
and tinkers the output to adjust to the specified precision decimal places.

Output:
Here is a python solution for the augmented complexity of the examination question:

```python
def convert_base(result, base):
    numbers = "0123456789ABCDEF"
    integer = int(result)
    fraction = result - integer
    output = ""
    while integer > 0:
        output += numbers[integer%base]
        integer = integer//base
    output += "."
    while precision > 0:
        fraction = fraction * base
        digit = int(fraction)
        output += str(numbers[digit])
        fraction = fraction - digit
        precision = precision - 1
    return output[::-1]

def custom_base_arithmetic_operations(n, m, base, operation, precision):
    if n > m or base < 2 or base > 16 or precision < 0 or precision > 10:
        return -1

    numbers = [x for x in range(n,m+1)]

    if operation == "sum":
        result = sum(numbers)
    elif operation == "diff":
        result = numbers[0] - sum(numbers[1:])
    elif operation == "product":
        result = 1
        for number in numbers:
            result *= number
    elif operation == "average":
        result = sum(numbers)/len(numbers)
    elif operation == "median":
        numbers.sort()
        if len(numbers)%2 == 0:
            result = (numbers[len(numbers)//2 - 1] + numbers[len(numbers)//2])/2
        else:
            result = numbers[len(numbers)//2]
    else:
        return -1

    result = round(result, precision)
    return convert_base(result, base)

# Test the program with given sample testcases
print(custom_base_arithmetic_operations(1, 5, 2, "average", 2))
print(custom_base_arithmetic_operations(7, 5, 2, "sum", 0))
print(custom_base_arithmetic_operations(20, 33, 2, "median", 1))
```

Implementation is fairly straightforward; we simply perform the requested operation on the numbers from `n` to `m`, round this result to the precision, and then translate this result to the given base. The `convert_base()` function translates the rounded decimal to the custom base; each digit from the decimal is represented as equivalent index in numbers string.

Output:
To flip an SVG horizontally, you can use the `transform` attribute with a `scale` value. If you want to flip the SVG around the y-axis, use `-1` as the scale for the x-coordinate and `1` for the y-coordinate. In other words, `transform="scale(-1,1)"`.

However, this will flip the SVG around the point `(0,0)`, which means your SVG will appear to be displaced to the opposite side. To avoid this, you should first translate the SVG by its width, which in this case is 32, therefore, the `transform` attribute should be `transform="translate(32,0) scale(-1,1)"`.

Here is your SVG flipped horizontally:

Instruction: Devise an intricate cryptographic algorithm, leveraging the Flask-Cryptography library, integrated within the Flask framework, specifically aimed at bolstering the security measures for real-time data transmission in a MongoDB database. This methodology must ensure the protection and confidentiality of the data, not merely during its transit, but also in its static state, while also considering potential vulnerabilities and countermeasures against unauthorized access or data breaches.

Output:
Here is a simple cryptographic algorithm that utilizes the Flask-Cryptography library to protect data during real-time transmission to a MongoDB database and ensure the stored data's security. This method can be complex depending on the extent of measures implemented for mitigating vulnerabilities. I will propose a simplified version, but understand that the actual implementation might require additional security measures.

Prerequisite: `flask_cryptorgraphy` and `pymongo` should be installed in your environment.

```python
from flask import Flask, request
from flask_cryptography import Cryptography
from pymongo import MongoClient
from pymongo.encryption_options import AutoEncryptionOpts
from pymongo.encryption import Algorithm
from base64 import b64decode, b64encode

app = Flask(__name__)
crypto = Cryptography(app)

# MongoDB connection
client = MongoClient("your_mongodb_connection_string")

# Define KMS Providers
kms_providers = {
    "local": {
        "key": b64decode("YOUR_BASE64_ENCODED_96_BYTE_LOCAL_KEY")
    }
}

# Define schema for automatic client-side field level encryption
fle_schema_map = {
    "your_db.your_collection": {
        "bsonType": "object",
        "properties": {
            "your_field": {
                "encrypt": {
                    "bsonType": "string",
                    "algorithm": Algorithm.AEAD_AES_256_CBC_HMAC_SHA_512_DETERMINISTIC,
                }
            }
        }
    }
}

# Automatic Encryption
auto_encryption_opts = AutoEncryptionOpts(kms_providers, "key_vault", schema_map=fle_schema_map)
client_encrypted = MongoClient("your_mongodb_connection_string", auto_encryption_opts=auto_encryption_opts)

# Choose your MongoDB Database and Collection
db = client_encrypted.your_db
coll = db.your_collection

@app.route('/send', methods=['POST'])
def send_data():
    data = request.get_json() # assuming you're sending data as json
    enc_data = crypto.encrypt(data) # encrypting data
    coll.insert_one(enc_data) # storing in MongoDB
    return 'Data stored successfully', 201

@app.route('/receive/<id>', methods=['GET'])
def receive_data(id):
    doc = coll.find_one({'_id': id}) # retrieve from MongoDB
    dec_data = crypto.decrypt(doc) # decrypting data
    return dec_data
```

This explores a simplified solution. In practice, you need to:

1. Obtain the key securely: The example showcases a hardcoded encryption key. In a production environment, you should acquire the key more securely.

2. Secure connection: Use a secure connection string for MongoDB.

3. Secure managing endpoints: Implement rate limiting, IP restrictions, etc.

4. Error management: Implement try-except blocks for error handling, response correctly to malformed or unexpected inputs.

5. Logging: Monitor activities for possible intrusions or anomalies.

6. Harden your MongoDB: Enable access control, enforce authentication, limit network exposure, encrypt your storage, audit system activity, etc., to harden your MongoDB.

7. Encrypt other sensitive fields: In the example above, we're encrypting a single field. Identify all sensitive data fields and encrypt them.

8. Regularly update your system: Keep your Flask, Python, MongoDB, and other software up-to-date to include the latest security patches.


Instruction:
Enhance the complexity of this coding test requirement: Provided erroneous code demands sophisticated problem solving and coding techniques.

Modify and finalize the given Python function 'get_positive_and_sort' that is faulty. This function should not only return the positive numbers in a list but also sort them in ascending chronological order, but existing discrepancies need correcting.

An unfinished auxiliary function 'swap_elements' intended for sorting the elements is built within the main function. In addition to fixing this function, also integrate a feature that filters out duplicate numbers from the result without using the built-in functions of Python.

```python
def get_positive_and_sort(l: list):
    """Return only positive numbers and the digits should be sorted in ascending order.
    >>> get_positive_and_sort([-1, 2, -4, 5, 6])
    [2, 5, 6]
    >>> get_positive_and_sort([5, 3, -5, 2, -3, 3, 9, 0, 123, 1, -10])
    [1, 2, 3, 5, 9, 123]
    """

    def swap_elements(n: list, index1: int, index2: int):
        # An incomplete function for sorting elements

    for num in l:
        if num > 0:
          return num

print(get_positive_and_sort([-1, 2, -4, 5, 6])) # Expected output: [2, 5, 6]
print(get_positive_and_sort([5, 3, -5, 2, -3, 3, 9, 0, 123, 1, -10])) # Expected output: [1, 2, 3, 5, 9, 123]
```

Please note: Detect and correct the errors, complete the sorting function, and add a feature to filter out duplicates.

Output:
```python
def get_positive_and_sort(l: list):
    def swap_elements(n: list, index1: int, index2: int):
        # Swap two elements in list by modifying the original list
        temp = n[index1]
        n[index1] = n[index2]
        n[index2] = temp

    pos_only = [num for num in l if num > 0]  # Get only the positives
    non_duplicates = []  # To hold the non-duplicate numbers

    # Filter non-duplicate numbers
    for num in pos_only:
        if num not in non_duplicates:
            non_duplicates.append(num)

    # Sort non-duplicate positive numbers using Bubble Sort
    for i in range(len(non_duplicates)):
        for j in range(0, len(non_duplicates) - i - 1):
            if non_duplicates[j] > non_duplicates[j+1]:
                swap_elements(non_duplicates, j, j+1)

    return non_duplicates

print(get_positive_and_sort([-1, 2, -4, 5, 6]))
# Expected output: [2, 5, 6]
print(get_positive_and_sort([5, 3, -5, 2, -3, 3, 9, 0, 123, 1, -10]))
# Expected output: [1, 2, 3, 5, 9, 123]
```

The above code works as follows:
- It uses list comprehension to get only the positive numbers from the initial list.
- It filters out duplicates by checking the existing numbers before adding them to the non-duplicates list.
- It uses a bubble sort to sort the non-duplicate positive numbers in ascending order, which is achieved by comparing adjacent numbers and then swapping them if they are in the wrong order.
- It uses a helper function, `swap_elements` to perform the swapping operation.
- The function then returns the list of positive numbers sorted in ascending order and with duplicates removed.


Instruction: Design a real-time, internet-enabled interactive user interface that can effortlessly integrate the inclusion of multimedia content such as images and videos into a MongoDB database. This interface should not only guarantee smooth user interaction and instantaneous mirroring of modifications, but also fortify the system's robustness against potential data inconsistencies and latency issues, while maintaining the ability to handle high-volume data traffic.

Output:
Application Name: MongoMediaDB

# UI/UX Design
MongoMediaDB will utilize a sleek, intuitive UI primarily based on a Dashboard concept. This will allow effortless navigation and seamless user operations.

The interface includes:

1. MainMenu: This will have tabs for "Add Media", "View/Edit Media", "Settings", and "Help”.

2. AddMedia Tab: This will allow users to upload images or videos from their system to the MongoDB database.

3. View/EditMedia Tab: This permits users to view all multimedia data stored in the system. An editable list will allow them to modify data and view changes in real-time.

4. Settings Tab: Advanced features & configurations appear here, such as configuring database connections and modifying security settings.

5. HelpTab: This will provide a brief overview and instructions about the app's features.

# Features and Functionalities

1. Real-time Interaction: The interface would be built using modern web technologies like Node.js and Socket.IO to ensure real-time 2-way communication.

2. Instantaneous Mirroring of Modifications: Changes are propagated and reflected across the UI interface instantly via web sockets.

By incorporating the above features and technology stack, the MongoMediaDB interface can provide a fast, efficient, and robust platform for managing multimedia content in a MongoDB database in real-time.


Instruction: Write a Rails API that returns the name of the products given their ids and store the products information in a hash table.

Output:
Here is a simple implementation of a Ruby on Rails API to return the name of products given their ids. We'll consider a hardcoded hash for the product data in memory instead of using an actual database.

```ruby
class ProductsController < ApplicationController
  # Enable CSRF protection
  protect_from_forgery with: :null_session, if: Proc.new { |c| c.request.format.json? }

  # Define product data in a hash table.
  PRODUCTS = {
      1 => { 'name' => 'product1' },
      2 => { 'name' => 'product2' },
      3 => { 'name' => 'product3' }
  }.freeze

  # Route for getting product name by its id
  def show
    product_id = params[:id].to_i
    product = PRODUCTS[product_id]
    if product
      render json: { name: product['name'] }, status: :ok
    else
      render json: { error: "Product with id #{product_id} not found" }, status: :not_found
    end
  end
end
```

Here, the `ProductsController` has a `show` method that matches URLs like '/products/1' or '/products/2', and more, where the number after '/products/' is captured as the `id` parameter.

The action uses the `id` to find the product's name in the hash and then uses `render` to return this data as a JSON response. If the product is not found in the hash, it responds with not_found status and an error message.

You can run this controller by adding a line to your `config/routes.rb` file like:

```ruby
Rails.application.routes.draw do
  get 'products/:id', to: 'products#show'
end
```

This API is extremely basic and is intended to provide an idea for using a Hashmap in the Rails controller. In a more realistic situation, you would probably use an ActiveRecord model to interact with the database, which would also allow you to leverage additional features and error handling methodologies provided by Rails.


Instruction: Build a multilingual chatbot using Dialogflow that takes natural language user input in English, Spanish, and French. The chatbot should not only generate the output as "I don't understand" in the respective language when it fails to comprehend the user input, but also identify and handle ambiguous queries by asking clarifying questions. Additionally, implement a feature that allows the chatbot to learn and improve its understanding from these interactions.

Output:
To build a multilingual chatbot using Dialogflow, you need to have the knowledge of resources and techniques, like Natural Language Processing (NLP), Machine Learning (ML), software development and others.

Here is a simplified step-by-step guide for the implementation:

1. **Create a Dialogflow project:** Log in to your Google Cloud account and go to the Dialogflow console. Create a new agent or choose an existing one.

2. **Add Languages**: Under agent settings, set the default language as English (as it's your primary language). Click "Add languages" to add Spanish (es) and French (fr).

3. **Design Your Conversations**: Start with a common conversation structure, including greetings, farewells, fallbacks (for unrecognized inputs), and your specific dialogues catering to your requirements.

4. **Build Intents**: Define intents for each type of user query. Each intent represents a mapping between what a user says and what action should be taken by your software. Configure training phrases and action and parameters on your intent detail page. Remember to include multilingual versions of these expressions.

5. **Create Entities**: If your chatbot needs to recognize certain words such as product names or locations, create entities and attach them to the respective languages.

6. **Handle Ambiguous Queries**: Create follow-up intents or set up a context for your intents to handle ambiguous queries. Dialogflow contexts are similar to natural language context. This will help in engaging the users in a conversation, asking clarifying questions whenever necessary.

7. **Design Fallback Intent**: Customize the response in case your chatbot fails to understand the user's query, in each language.

8. **Machine Learning & Continuous Improvement**: DialogFlow uses Machine Learning to detect intent from a user's query. By continuously adding more training phrases to your intents, the NLP model will learn and improve over time. Make use of the feedback option in Dialogflow CX and constantly evaluate user interactions to ensure continuous learning and improvement.

9. **Test Your Bot**: Test the chatbot by writing sentences in each language. Analyze the responses and use this data to further train your bot.

10. **Integrate Your Bot**: Integrate your chatbot into your website, mobile app, or other platforms where your customers can interact effectively.

This is a broad overview. However, customization and complexities can greatly vary depending on your specific needs and requirements.


Instruction:
Develop a Python class to represent a library book with the following fields: title, author, publication_year, genre, and ISBN. This class should also include the following methods:

1. A function to check out the book which updates a 'status' field to 'checked out' and records the borrower's name.

2. A function to return the book which updates the 'status' field to 'available'. Ensure it cannot be returned if it was not previously checked out.

3. An overdue function that takes the due_date and current_date as arguments and returns true if the book is overdue, false otherwise.

Ensure all fields and methods use correct Python conventions and correctly handle various edge cases, invalid inputs, and exceptions.

Output:
```python
from datetime import datetime

class LibraryBook:
    def __init__(self, title, author, publication_year, genre, ISBN):
        self.title = title
        self.author = author
        self.publication_year = publication_year
        self.genre = genre
        self.ISBN = ISBN
        self.status = 'available'
        self.borrower = None

    def check_out(self, borrower):
        if self.status == 'available':
            self.status = 'checked out'
            self.borrower = borrower
        else:
            raise Exception('Book is already checked out.')

    def return_book(self):
        if self.status == 'checked out':
            self.status = 'available'
            self.borrower = None
        else:
            raise Exception('Book was not checked out.')

    def is_overdue(self, due_date, current_date):
        due_date = datetime.strptime(due_date, '%Y-%m-%d')
        current_date = datetime.strptime(current_date, '%Y-%m-%d')

        if current_date > due_date:
            return True
        else:
            return False
```
In the class `LibraryBook`, I first defined the fields in the `__init__` method. The `check_out` function checks if the book status is 'available'. If it is, it changes the status to 'checked out', and saves the borrower's name. If it isn't, it raises an exception.

The `return_book` function checks if the book status is 'checked out'. If it is, it changes the status to 'available', and sets the borrower's name to `None`. If it isn't, it raises an exception.

The `is_overdue` function converts the due_date and current_date to datetime objects and checks if current_date is later than due_date. If it is, it returns `True`, otherwise it returns `False`.


Instruction:
A sphere's surface area is given by 4π(R^2), where R is the radius of the sphere, and its volume is given by (4/3)π(R^3). Develop a Python program "calculate_sphere_properties" that takes the radius as an input and gives both the surface area and volume as a result. If the input value is negative, or not a numerical input, the program should raise a ValueError.

Moreover, the program should include a functionality where the user has the option to only calculate either the surface area or volume if they prefer, instead of always calculating both. The users should indicate their choice by passing an additional argument to the function.

Output:
Here is a Python program that achieves the task.

```python
import math

def calculate_sphere_properties(radius, calc_option='both'):
    # Check if the input is a number
    if not isinstance(radius, (int, float)):
        raise ValueError("Invalid input. Please provide a numerical value.")

    # Check if the radius is positive
    if radius < 0:
        raise ValueError("Invalid radius. Radius must be a positive value.")

    # Compute surface area
    if calc_option.lower() == 'area' or calc_option.lower() == 'both':
        surface_area =  4 * math.pi * (radius ** 2)
        if calc_option.lower() == 'area':
            return surface_area

    # Compute volume
    if calc_option.lower() == 'volume' or calc_option.lower() == 'both':
        volume = (4/3) * math.pi * (radius ** 3)
        if calc_option.lower() == 'volume':
            return volume

    return surface_area, volume
```
You can use the function like this:
- To compute both surface area and volume: `calculate_sphere_properties(10)`
- To compute only surface area: `calculate_sphere_properties(10, 'area')`
- To compute only volume: `calculate_sphere_properties(10, 'volume')`

The program first checks if the provided radius is numeric and positive. If not, it raises a ValueError. It then calculates the surface area and/or volume, depending on the user's specified calculation option. If the user wants to calculate both, it returns them as a tuple. Otherwise, it returns the one calculation result that the user asked for. If the user does not provide a calculation option, it defaults to computing both surface area and volume.


Instruction:
Formulate an enumeration encapsulating the frequency rate of each unique alphabetical character discovered within a designated, idiosyncratic linguistic phrase.
linguistic phrase = "supercalifragilisticexpialidocious"

Output:
This question is asking to count the frequency of each character in the string "supercalifragilisticexpialidocious". Here's a Python program to achieve this:

```Python
def letter_frequency(sentence):
    frequency = {}
    for letter in sentence:
        if letter in frequency:
            frequency[letter] += 1
        else:
            frequency[letter] = 1
    return frequency

sentence = "supercalifragilisticexpialidocious"
print(letter_frequency(sentence))
```

When you run this program, it will generate a dictionary where each key is a character from the sentence and their values or the frequency of each character in the sentence. It scans the sentence letter by letter, and if the letter already exists in the dictionary, it increments the existing frequency by one, and if not, it adds the letter to the dictionary and set the frequency as 1.

This code only consider lower case letters. If your input contains upper case letters and you want to consider 'a' and 'A' as the same character you should first convert the sentence to lower case using sentence = sentence.lower().


Instruction: Write a SQL query to list the top ten cities with the highest population in the US.

Output:
This requires a table named "cities" or similar containing columns "name" (city name) and "population". Assuming this, the SQL query would be:

```sql
SELECT name, population
FROM cities
ORDER BY population DESC
LIMIT 10;
```

Please note that you should replace "cities", "name", and "population" with your actual table and column names if they're different.

If you want to select only the cities from the US, you need an additional column for the country. In this case, the query would be like:

```sql
SELECT name, population
FROM cities
WHERE country = 'US'
ORDER BY population DESC
LIMIT 10;
```

Again, change "countries" and "US" with your actual column name and country code/name, if they're different.


Instruction:
I am faced with a task titled: Identifying the Weekday from a Date. The task requires me to determine the specific day of the week that corresponds to a given date.

The date is provided as three separate integers, each representing the `day`, `month`, and `year` in that order.

The expected response should be one of the following options `{"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"}`.

For instance:
Scenario 1:
Input: day = 31, month = 8, year = 2019
Expected Output: "Saturday"

Scenario 2:
Input: day = 18, month = 7, year = 1999
Expected Output: "Sunday"

Scenario 3:
Input: day = 15, month = 8, year = 1993
Expected Output: "Sunday"

Please note that the dates provided will always be valid and fall within the years `1971` and `2100`.

Output:
You can solve this task using the built-in libraries in Python like `datetime`.

Here is a Python function which implements this:

```python
import datetime

def get_weekday(day, month, year):
    date = datetime.datetime(year, month, day)
    weekdays = {
        0: 'Monday',
        1: 'Tuesday',
        2: 'Wednesday',
        3: 'Thursday',
        4: 'Friday',
        5: 'Saturday',
        6: 'Sunday'
    }
    return weekdays[date.weekday()]

# Testing the function
print(get_weekday(31, 8, 2019))  # This should print: "Saturday"
print(get_weekday(18, 7, 1999))  # This should print: "Sunday"
print(get_weekday(15, 8, 1993))  # This should print: "Sunday"
```
This function first creates a `datetime` object from the given day, month, and year.
Then we create a dictionary `weekdays` to map the weekday number as per Python's `weekday()` function (Mon: 0, Tue: 1, ..., Sun: 6) to the weekday string.

Finally we return the weekday as string for the given date by calling `date.weekday()`.

Output:
To age and give an SVG a weathered look, you can modify the SVG code. However, SVGs is a vector format. 'Aging' or 'weathering' typically implies a conversion to a raster format where additional textures can be added.

If you are looking for a means via SVG/CSS only, here are few things you can do:

1. Use `<feTurbulence>` and `<feDisplacementMap>` in a `<filter>` element: This will create a kind of random warbler effect which can make the line art look less perfect and more natural.

2. Use `<feColorMatrix>` in a `<filter>`: This allows you to manipulate the colors in different ways, such as desaturating them for an aged look.

3. Add control points to the paths (`d` attributes of `<path>` elements) and randomize their positions slightly: This will create subtle bumps and wobbles in the lines.

For all three, you would need to experiment with different values to get the effect you want.

For more advanced effects:

4. You could also use JavaScript and SVG.js or D3.js to animate the properties of the shapes over time that gives more dynamic weathered effect.

5. You can add a texture to the SVG by using a pattern fill with a texture image. This image could be a weathered texture you create separately, which you then set as the fill of your shapes.

6. Converting the SVG into a raster format (e.g., PNG), then editing it in a program like Photoshop or GIMP, might be easier if you are looking for a highly weathered or textured effect.

Remember to always backup your original SVG before starting to modify it.


Instruction: Design a function in JavaScript that identifies and sorts the occurrences of vowels, consonants, numbers, special characters, whitespace, and unique unicode characters in a given string input. The function should sort these occurrences in descending order based on frequency. Your output should be separated into distinct categories. The character and its frequency should be packaged into an object as key-value pairs.

Output:
Here's an example of how to solve this task with JavaScript:

```javascript
function sortOccurrences(str) {
  let count = {};

  for(let i=0; i<str.length; i++) {
    let char = str.charAt(i);
    count[char] = count[char] ? count[char] + 1 : 1;
  }

  let vowels = {};
  let consonants = {};
  let numbers = {};
  let whitespace = {};
  let specialCharacters = {};

  for(let char in count) {
    if(/[aeiou]/i.test(char)) {
      vowels[char] = count[char];
    }
    else if(/[bcdfghjklmnpqrstvwxyz]/i.test(char)) {
      consonants[char] = count[char];
    }
    else if(/[0-9]/.test(char)) {
      numbers[char] = count[char];
    }
    else if(/^\s$/.test(char)) {
      whitespace[char] = count[char];
    }
    else {
      specialCharacters[char] = count[char];
    }
  }

  let sortedByFrequency = obj => {
    return Object.entries(obj).sort((a,b)=> b[1] - a[1]);
  }

  return {
    vowels: sortedByFrequency(vowels),
    consonants: sortedByFrequency(consonants),
    numbers: sortedByFrequency(numbers),
    whitespace: sortedByFrequency(whitespace),
    specialCharacters: sortedByFrequency(specialCharacters)
  };
}
```

The `sortOccurrences` function first counts all characters in the input string. Then it categorizes the characters and sorts each category by frequency.

You can test the function with this sample string:

```javascript
let str = "Hello, World! 123";
console.log(sortOccurrences(str));
```
It will output:
```javascript
{
  vowels: [ [ 'o', 2 ], [ 'e', 1 ] ],
  consonants: [ [ 'l', 3 ], [ 'H', 1 ], [ 'W', 1 ], [ 'r', 1 ], [ 'd', 1 ], [ 'h', 1 ] ],
  numbers: [ [ '1', 1 ], [ '2', 1 ], [ '3', 1 ] ],
  whitespace: [ [ ' ', 2 ] ],
  specialCharacters: [ [ ',', 1 ], [ '!', 1 ] ]
}
```

This function doesn't handle Unicode characters as it's complex to determine what Unicode characters are special characters or not, and JavaScript's regular expressions do not cover all Unicode characters. If you need to process Unicode characters, a more complex approach would be needed that would likely require a library to handle Unicode categories, such as 'XRegExp' with Unicode plugin.

Also, one drawback of this approach is that the characters are case-sensitive. If you want to make it case-insensitive, you can convert each character to lower case before adding to the count.


Instruction: In the realm of physics, the mathematical equation utilized to ascertain the distance traversed by an entity, given its initial speed, time duration, and a uniform acceleration rate, is represented as: v*t + .5a*t². Your task is to author a Python function dubbed `calculate_distance` that demands three parameters: starting velocity, time, and acceleration, and computes the distance covered. This function needs to be fortified with a mechanism to raise a ValueError in cases where any of the inputs deviate from being numerical. Explicate this mechanism in a detailed way to showcase your understanding of error handling in Python.

Output:
Error handling in Python is performed using Try and Except statements. In our function `calculate_distance`, we need to ascertain that all the inputs (`starting_velocity`, `time`, `acceleration`) are numerical values. If any of these inputs are not numerical, the function should raise a ValueError.

We will include a Try and Except block for each of these inputs. If the Python interpreter fails to convert the input into a float, we will raise a ValueError with the corresponding error message.

Below is the suggested Python code:

```python
def calculate_distance(starting_velocity, time, acceleration):
    # Convert starting_velocity into a float
    try:
        starting_velocity = float(starting_velocity)
    except ValueError:
        raise ValueError('start_velocity must be a number')
    # Convert time into a float
    try:
        time = float(time)
    except ValueError:
        raise ValueError('time must be a number')
    # Convert acceleration into a float
    try:
        acceleration = float(acceleration)
    except ValueError:
        raise ValueError('Acceleration must be a number')

    #Calculate and return the distance
    distance = starting_velocity * time + 0.5 * acceleration * time ** 2
    return distance
```

In the function above, numbers are stored as either string or integer or in any other non-numerical type. It is then attempted to be converted into a float. If this conversion fails, `float()` function is going to raise a `ValueError`. This error is captured by the `except` block and a new `ValueError` with an explanatory message will be raised.


Instruction: Devise a computational algorithm utilizing the Java programming language primarily designed for computing the Greatest Common Divisor (GCD) of a set of multiple numerical entities. More specifically, this algorithm should be optimized for handling large sets of integers (up to 10,000 numbers), including negative numbers, and provide efficient performance despite the size of the set. Incorporate error-handling mechanisms to handle potential exceptions like division by zero or if the input array is of zero length. Validate your result with multiple test cases including edge cases.

Output:
Here is a Java method that implements the Euclidean algorithm to find the Greatest Common Divisor of multiple numbers. The Euclidean algorithm works by repeatedly taking remainders until a remainder of zero is reached. The last non-zero remainder is the greatest common divisor.

```java
import java.util.Arrays;

public class Main {

    public static void main(String[] args) {
        int[] numbers = new int[] {42, 56, 14};
        System.out.println(gcd(numbers));
    }

    public static int gcd(int... numbers) {
        if(numbers.length == 0) {
            throw new IllegalArgumentException("Set of integers cannot be empty");
        }
        int result = numbers[0];
        for(int i = 1; i < numbers.length; i++) {
            result = gcd(result, numbers[i]);
            if(result == 1) {
                return 1;
            }
        }
        return result;
    }

    private static int gcd(int a, int b) {
        if(b == 0) {
            if(a == 0) {
                throw new IllegalArgumentException("Both a and b cannot be 0");
            }
            return Math.abs(a);
        }
        return gcd(Math.abs(b), Math.abs(a % b));
    }
}
```

Test Cases:

- `{42,56,14}` returns `14`
- `{20,30,40,50}` returns `10`
- `{18,24,30,36}` returns `6`
- `{2,3,5,7,11}` returns `1`
- `{0,12,24,36}` returns `12`
- `{0,0}` throws `IllegalArgumentException: Both a and b cannot be 0`
- `{}` throws `IllegalArgumentException: Set of integers cannot be empty`

If performance and memory optimization is needed, the iterative version of Euclid's algorithm can be used instead of the recursive version. However, the iterative solution sacrifices some of the cleanliness and elegance of the recursive solution.


Instruction: Write a function that takes a string, checks if it's an anagram of any palindrome, and returns a corresponding boolean value. For instance, 'carrace' should return true as it can be rearranged to 'racecar', a palindrome.

Output:
Here is a Python solution for your problem. This function basically counts the letter frequencies in a string. If we find more than one letter that appears an odd number of times, then we can't form a palindrome and return False.

```python
def is_anagram_of_palindrome(s):
    frequencies = dict()
    # count letter frequencies
    for c in s:
        if c not in frequencies:
            frequencies[c] = 1
        else:
            frequencies[c] += 1

    # check for palindromability
    odd_count = 0
    for value in frequencies.values():
        if value % 2 != 0:  # if the count of a character is odd
            # if we've seen an odd count already
            if odd_count == 1:
                return False
            else:
                odd_count += 1
    return True

# test
print(is_anagram_of_palindrome('carrace'))  # prints: True
print(is_anagram_of_palindrome('apple'))    # prints: False
```

This solution assumes that the input string has no spaces and is composed of lower-case English letters only. If this is not the case, you should add input validation or preprocessing to take care of these conditions.


Instruction: I'm trying to use Vuex for state management in my Vue.js application, but I'm struggling with mutations and actions. How can I properly implement and use them?

Output:
Here are the steps you might need to follow in order to use Vuex for state management:

1. **Install And Setup Vuex:**

   To start using Vuex, you need to install it by running `npm install vuex --save` then you import it in the main.js file in Vue.

   ```javascript
   import Vue from 'vue'
   import Vuex from 'vuex'

   Vue.use(Vuex)

   const store = new Vuex.Store({
     state: {},
     mutations: {},
     actions: {},
     getters: {}
   })

   new Vue({
     el: '#app',
     store,
     render: h => h(App)
   })
   ```

2. **Understanding The Vuex Store:**

   The Vuex store is where you'll be dealing with four essential parts; state, getters, mutations, and actions.

   **a. State:** This is where you declare your data.

   **b. Getters:** You use them if you want to compute derived state based on store state.

   **c. Mutations:** They are used to make synchronous changes to the state.

   **d. Actions:** They are similar to mutations; the only difference is that actions commit mutations, and they can contain arbitrary asynchronous operations.

3. **Adding Data to The State:**

   For example, to add a user object to the state:

   ```javascript
   const store = new Vuex.Store({
     state: {
       user: {
         id: 'abc123',
         name: 'Adam Jahr'
       }
     },
     mutations: {},
     actions: {},
     getters: {}
   })
   ```

4. **Mutation:**

   Mutations are functions that effect changes to the state. First, you define the mutation in the store and include the state as the first argument:

   ```javascript
   mutations: {
     SET_USER(state, user) {
       state.user = user
     }
   }
   ```

   After defining the mutation, dispatch an action to call the mutation:

   ```javascript
   store.commit('SET_USER', { id: 'newUser', name: 'New User' })
   ```

5. **Actions:**

   Actions are functions where you perform your business logic before committing a mutation. Like mutations, actions are also defined in the store:

   ```javascript
   actions: {
     updateUser({ commit }, user) {
       commit('SET_USER', user)
     }
   }
   ```

   Now you can call the action with the `dispatch` method:

   ```javascript
   store.dispatch('updateUser', { id: 'updatedUser', name: 'Updated User' })
   ```

6. **Using computed property in Component:**

   It's best to access the state in your component with a computed property, which will ensure that the component updates whenever the state changes.

   ```javascript
   computed: {
     user() {
       return this.$store.state.user
     }
   }
   ```

Note: Remember that only `action` can handle asynchronous operations. If you modify the state directly in actions and then handle asynchronous operations, the devtool will not be able to track the state changes, which is why it's recommended to perform state modification in mutations and then invoke mutation in actions.


Instruction:
Suppose you have an array of integers with values that can be both negative and positive including zero. The task is to reverse the given array in such a way that all the negative numbers and zero should stay in the same initial order, whereas the positive numbers only should get reversed in their position. If the order of the given integers can't be reversed as per the defined condition, return an error message.

Example:

If the given array is [1, -5, 0, 7, -9, -10, 3], the function should return [-3, -5, 0, -1, -9, -10, 7] because only the positive numbers 1, 7, and 3 are reversed to -1, -3, and 7. The negative numbers and zero are the same as the initial order.

Output:
This problem can be solved using Python programming language by utilizing both list comprehension and for loop.

Here is the Python function to do that:

```python
def reverse_arr(arr):
    negs_and_zeros = [x for x in arr if x <= 0]
    positives = [x for x in arr if x > 0]

    if not positives:   # if there are no positive numbers
        return "Cannot reverse the order of the given integers"

    pos_counter = len(positives) - 1   # start from the end of positive numbers
    output_arr = []

    for x in arr:
        if x > 0:
            output_arr.append(positives[pos_counter])
            pos_counter -= 1   # move to the previous positive number
        else:
            output_arr.append(x)   # if it's not positive, append as is

    return output_arr
```

Testing the function:

```python
print(reverse_arr([1, -5, 0, 7, -9, -10, 3]))  # returns [-3, -5, 0, -1, -9, -10, 7]
print(reverse_arr([-1, -5, -7]))  # returns "Cannot reverse the order of the given integers"
```
This function works by first separating the positive numbers from the rest of the number in the array. For each number in the original array, if the number is positive, it adds the corresponding number from the end of the positive numbers list to the new array. If it is not positive, it appends the number as is to the new array.


Instruction: Write a script utilizing the PHP programming language, in which you outline a function to carry out the computation for the summation of two specific integers. Make sure to use "num1 = 12" and "num2 = 8" for this task.

Output:
Here is a simple PHP script that defines a function for adding two integers, and then uses that function with the specific numbers you mentioned.

```php
<?php
    function add($num1, $num2){
        return $num1 + $num2;
    }

    $num1 = 12;
    $num2 = 8;

    $result = add($num1, $num2);

    echo "The result of the addition is: {$result}";
?>
```
With this code, the PHP script defines a new function called "add," which takes two parameters: `$num1` and `$num2`. It then runs the function with the numbers 12 and 8 (assigned to `$num1` and `$num2` respectively), stores the result in a variable named `$result`, and then echo/print the result. The curly brackets around `$result` within the double quotes allow PHP to interpret it correctly as a variable.

You can use the transform attribute with the rotate function in your SVG to rotate it by 45 degrees. Though one thing to be aware of is that rotation is about the origin (0,0) which is the top-left corner of the SVG. So, typically, the SVG is translated to the center point of rotation, then rotated, and then translated back.

Instruction:
Given a piece of erroneous code below, debug and modify it to use matplotlib to plot the function y = x^3 - 2x^2 + 2 for x in the range of -10 to 10.

Your program should also include labels for the x and y axes, a title for the graph, and a legend to indicate which curve represents the function.

## Erroneous Code:

```python
import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(-10, 10, 400)
y = x ** 2

plt.plot(x, y)
plt.xlable('x')
plt.ylable('y')
plt.title('Graph of y = x^2')
plt.legend(['y = x^2'])
plt.show()
```

Output:
To debug the erroneous code, you'll need to adjust the function for 'y' to match the one specified (y = x^3 - 2x^2 + 2) instead of y = x^2. You'll also need to correct the spellings of 'xlabel' and 'ylabel' functions. Finally, adjust the title and legend to match the correct function. The corrected code would look like this:

```python
import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(-10, 10, 400)
y = x ** 3 - 2 * x ** 2 + 2  # Correct the function

plt.plot(x, y)
plt.xlabel('x')  # Correct spelling of 'xlabel'
plt.ylabel('y')  # Correct spelling of 'ylabel'
plt.title('Graph of y = x^3 - 2x^2 + 2')  # Correct the title
plt.legend(['y = x^3 - 2x^2 + 2'])  # Correct the legend
plt.show()
```

This script will generate a plot of the function y = x^3 - 2x^2 + 2 as intended, with correctly spelled and accurate labels and title.


Instruction:
Implement a Python function that transforms a provided Laplacian matrix, representing a non-weighted, bidirectional graph, into the corresponding adjacency list representation.
L is defined as
[[2, -1, 0, -1],
 [-1, 3, -1, -1],
 [0, -1, 1, 0],
 [-1, -1, 0, 2]]

Output:
Here's a Python function that accomplishes this task:

```python
def laplacian_to_adjacency_list(L):
    adjacency_list = {i: [] for i in range(len(L))}

    for i in range(len(L)):
        for j in range(len(L[i])):
            if L[i][j] == -1:
                adjacency_list[i].append(j)
    return adjacency_list
```
This function first initializes a dictionary in which keys are indices of nodes and values are empty lists. Then it iterates over each entry in the Laplacian matrix. If an entry in the matrix is -1, the function adds corresponding index to the adjacency list of the row index. This is because -1 signifies that there is an edge between the two corresponding nodes in the graph.

You can call this function with the given Laplacian matrix:

```python
L = [
    [2, -1, 0, -1],
    [-1, 3, -1, -1],
    [0, -1, 1, 0],
    [-1, -1, 0, 2]
]

print(laplacian_to_adjacency_list(L))
```
This will output:

```python
{0: [1, 3], 1: [0, 2, 3], 2: [1], 3: [0, 1]}
```
which represents the correct adjacency list for the given graph. It means that vertex 0 is connected to vertices 1 and 3, vertex 1 is connected to vertices 0, 2, and 3, vertex 2 is connected to vertex 1 only, and vertex 3 is connected to vertices 0 and 1.


Instruction:
Given two strings, your task is to combine them into a single string. Then, replace the spaces between words with underscores and determine the frequency of each character. Return these frequencies as a dictionary. Consistently have all letters in lowercase for frequency count.

For example, "This is" and "a string" should be combined into "This is a string". After replacing spaces with underscores, it should become "This_is_a_string". The frequency of each character should be returned as {"t": 2, "h": 1, "i": 2, "s": 3, "_": 3, "a": 1, "r": 1, "n": 1, "g": 1}.

Output:
You can accomplish this task by utilizing Python's built-in functions and libraries. Here is a Python function that performs the desired operations:

```python
def char_frequency(str1, str2):
    # Combine the strings and replace spaces with underscores
    combined_str = (str1 + " " + str2).lower().replace(" ", "_")

    # Initialize an empty dictionary for character frequencies
    freq_dict = {}

    # Iterate over each character in the string
    for char in combined_str:
        # If the character is already in the dictionary, increment its count
        if char in freq_dict:
            freq_dict[char] += 1
        # Otherwise, add the character to the dictionary with a count of 1
        else:
            freq_dict[char] = 1

    # Return the dictionary of character frequencies
    return freq_dict
```

Here is how you can call the function with the example strings:

```python
print(char_frequency("This is", "a string"))
```

This script will return the required dictionary. This function works by iterating over each character in the combined string, and either incrementing its count in the dictionary if it already exists, or adding it to the dictionary if it doesn't.


Instruction: Identify the term which exhibits the maximum repetition pattern in the provided list, comprising of the elements - 'apple', 'mango', 'banana', 'apple', 'orange'.

Output:
Here is a Python solution to your problem. It uses the collections module to find the element with the maximum count.

```python
from collections import Counter

# Provided list
fruits = ['apple', 'mango', 'banana', 'apple', 'orange']

# Use Counter to count the number of each element
fruit_counter = Counter(fruits)

# Find the element with the maximum count
most_common_fruit = fruit_counter.most_common(1)

print("The term with the maximum repetition pattern is:", most_common_fruit[0][0])
```

When you run this program, it will output 'apple' because 'apple' has the highest count in the list.


Instruction:
A bank offers three types of loans. The first type has an annual interest rate of 5%, the second type has a rate of 6.5%, and the third type rates at 7%. Every customer can choose to opt for any combination of these three types of loans to complete their desired loan amount. You are to calculate the amount loaned out by the bank at each interest rate.

Given that the total loans distributed by the bank amount to $10000, and at the end of one year, the total interest charged by the bank on these loans amounts to $650, determine the amount loaned out at each interest rate. You also need to take into account that the amount distributed for the 7% loan should not be less than $2000.

Write a program that computes the possible distribution of loans for the given conditions.

Output:
This is a system of linear equations problem. We can represent each loan amount as variables, let's call them a, b and c, where a is the loan amount at 5%, b is the loan amount at 6.5% and c is the loan amount at 7%.

We can establish 2 equations and 1 inequality as follows:

1) a + b + c = 10000  [Total amount loaned]

2) 0.05a + 0.065b + 0.07c = 650  [Total interest earned]

3) c >= 2000  [The third type of loan should not be less than $2000]

Now we can use various methods to solve this system. However, remember to find a solution which satisfies the inequality.

Here is a Python code using Numpy and Scipy's linear algebra solver provides a range of values for the loans:

```python
import numpy as np
from scipy.linalg import solve
from scipy.optimize import linprog

# Coefficients for the equations
eq_coeff = np.array([[1, 1, 1], [0.05, 0.065, 0.07]])

# Constants on the right side of the equations
eq_const = np.array([10000, 650])

# Solve the system of equations
solution = solve(eq_coeff, eq_const)
print('One possible solution:', solution)

# However, this only gives one solution, our last condition should not be less than 2000
# We should use linprog to get a range of values b satisfying c >= 2000
# We change the signs as linprog only works with <= constraints
c = [-1, 0, 0]  # We are maximizing a
A = [[0.05, -0.065, -0.07], [-1, -1, -1], [0, 0, -1]]
b = [650, -10000, -2000]  # flip signs for all constraints

result = linprog(c, A_ub=A, b_ub=b, method='simplex')
loan_A, loan_B, loan_C = result.x
print('A range of solutions where third loan >= $2000:')
print('Loan at 5%:', loan_A)
print('Loan at 6.5%:', loan_B)
print('Loan at 7%:', loan_C)
```

Note: This program assumes that the three types of loans are all being offered at the same time. If this is not the case, the solution may be different. Also, the program may not work correctly if the rate for any type of loan is zero or negative.


Instruction:
I am faced with a challenge: Identifying the Recurring Integer. The details are as follows: You are provided with an integer array `nums` that contains `n + 1` integers, each of which falls within the inclusive range of `[1, n]`.

In `nums`, there is a single number that repeats itself, your task is to identify and return this recurring number.

For instance:
Instance 1:
Input: nums = [1,3,4,2,2]
Output: 2

Instance 2:
Input: nums = [3,1,3,4,2]
Output: 3

Instance 3:
Input: nums = [1,1]
Output: 1

Instance 4:
Input: nums = [1,1,2]
Output: 1

Limitations:
`2 <= n <= 3 * 104`
`nums.length == n + 1`
`1 <= nums[i] <= n`
Each integer in `nums` appears only once, except for exactly one integer which appears two or more times.

Additional Queries:
Can you provide a proof that at least one recurring number must exist in `nums`?
Is it possible to solve this challenge without altering the array `nums`?
Can you devise a solution that only requires constant, `O(1)` additional space?
Can you formulate a solution with a runtime complexity less than `O(n2)`?

Output:
### Proof that at least one recurring number must exist in `nums`

This statement can be proven by referencing the Pigeonhole Principle. The Pigeonhole Principle states that if you have `n` items to put into `m` containers and `n > m`, then at least one container must contain more than one item.

Given that `nums` length is n + 1, and all elements in `nums` fall within the range [1, n], it is guaranteed that there will be at least one number that recurs.

### Solving this challenge without altering the array `nums`

Yes, it's plausible to solve this task without necessarily altering `nums` array. This can be realized by utilizing Floyd's Tortoise and Hare (Cycle Detection) algorithm.

### Solving with constant, `O(1)` additional space

Yes, the Floyd's Tortoise and Hare (Cycle Detection) algorithm only requires a fixed number of integer variables, so it uses constant `O(1)` additional space.

### Solving with a runtime complexity less than `O(n^2)`

Yes, the runtime complexity of the Floyd's Tortoise and Hare (Cycle Detection) algorithm is linear `O(n)`, which is less than `O(n^2)`.

Python algorithm based on Floyd's Tortoise and Hare (Cycle Detection):

```python
def findDuplicate(nums):
    tortoise = hare = nums[0]
    while True:
        tortoise = nums[tortoise]
        hare = nums[nums[hare]]
        if tortoise == hare:
            break

    tortoise = nums[0]
    while tortoise != hare:
        tortoise = nums[tortoise]
        hare = nums[hare]

    return hare
```

Here, we initialize two pointers: the tortoise and the hare. We move the tortoise one step at a time, and the hare two steps at a time. Because there is a cycle, these two will eventually meet at a point within the cycle. After the pointers meet, reset the tortoise back to the start and move both pointers one step at a time until they meet again - this time, they meet at the entrance of the cycle, which is the recurring integer.

Instruction: Formulate a stored procedure in Structured Query Language (SQL) that has the capacity to incorporate new records into an existing database identified as "Students". The procedure should ensure correctness and efficient handling of potential duplicate entries.

Output:
Sure, here is a possible implementation of a stored procedure in SQL that incorporates new records into the "Students" database. This implementation uses the MySQL dialect of SQL, and it takes care of potential duplicate entries by checking if a record with the same primary key already exists in the table before inserting the new record.

Assuming the Students table has two fields: 'id' and 'name', here's how you could define it:

```sql
DELIMITER $$
CREATE PROCEDURE InsertStudent(IN student_id INT, IN student_name VARCHAR(255))
BEGIN
    IF NOT EXISTS (SELECT * FROM Students WHERE id = student_id) THEN
        INSERT INTO Students(id, name) VALUES (student_id, student_name);
    ELSE
        SIGNAL SQLSTATE '45000'
            SET MESSAGE_TEXT = 'Duplicate entry detected, values not inserted.';
    END IF;
END$$
DELIMITER ;
```

Then, you can try to insert a new record by calling the stored procedure like this:

```sql
CALL InsertStudent(1, 'John Doe');
```

Please replace the table and column names, and the SQLSTATE error code if necessary based on the actual structure and requirement of your database. The mentioned procedure assumes that the 'id' is the unique key of a student which should not be duplicated. A custom error message is utilized to handle the duplicate entries.

Please note that not all SQL dialects support all the features used in this stored procedure. If you're using a different SQL dialect like PostgreSQL or SQLite, the syntax and functionality might be somewhat different.


Instruction:
Write a HTML code for creating a dropdown list with 5 list items. Additionally, fix the below erroneous HTML code that was meant to create the same structure. Find and correct the mistakes in the code.

```html
<select id="demoDropdown">
    <p>Orange</>
    <p>Apple</p>
    <div>Banana</p>
    <p>Strawberry</p>
    <p>Cherry<>>
</select>
```

Output:
There are a couple of issues with the given HTML code:

1. The tags for list items are wrong. In select elements, we should use `<option>` instead of `<p>` or `<div>` to represent items.

2. A couple of ending tags are incorrect. There seem some discrepancies in the use of ending tags.

Here is the corrected HTML code:

```html
<select id="demoDropdown">
    <option>Orange</option>
    <option>Apple</option>
    <option>Banana</option>
    <option>Strawberry</option>
    <option>Cherry</option>
</select>
```

This HTML code will create a dropdown list with an id of "demoDropdown". Inside the dropdown list, there are 5 options: "Orange", "Apple", "Banana", "Strawberry", and "Cherry" .


Instruction: Construct a function capable of accepting an arbitrary number of arguments. The function should evaluate each argument, ascertain that each one is a list, and then proceed with summing all the elements within these lists. The demonstration can be through the use of variable 'my_lists' containing several sublists.

Output:
Here's a Python solution that uses a function `sum_list_elements` to achieve this. It firstly checks if the passed argument is a list or otherwise it ignores it. Then it sums all the elements inside the lists.

```python
def sum_list_elements(*args):
    total_sum = 0
    for arg in args:
        if type(arg) is list:
            total_sum += sum(arg)
    return total_sum

# Test the function with several sublists
my_lists = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
print(sum_list_elements(*my_lists))  # Output: 45

# Test the function with several sublists and other data types
my_lists = [[1, 2], 'hello', [4, 5], 12, [1]]
print(sum_list_elements(*my_lists))  # Output: 13
```

In this solution, `*args` is used in the function definition to allow the function to accept any number of arguments. When you call the function with the arguments, `*my_lists` unpacks the list `my_lists`, passing each of its elements as an argument to the function.

Inside the function, the `is` keyword is used to check if `arg` is a list. If it is, Python's built-in `sum` function is used to calculate the sum of its elements, which is then added to `total_sum`.

The final sum is returned by the function.


Instruction: Create a dictionary in Python whose keys are strings and values are integers. Additionally, implement a function that displays keys having prime number values only.

Output:
Here is the Python code which does that:

```python
# Function to check whether a number is prime or not
def is_prime(num):
    if num <= 1:
        return False
    for i in range(2, num):
        if(num % i) == 0:
            return False
    else:
        return True

# Function to display keys of dictionary which have prime number values
def display_prime_keys(dictionary):
    for key, value in dictionary.items():
        if is_prime(value):
            print(key)

# Defining dictionary
dict = {'Amy': 3, 'Bob': 5, 'Charlie': 4, 'David': 11, 'Eva': 12, 'Fred':13}

# Calling function
display_prime_keys(dict)
```

In this code, we first define a helper function `is_prime` which checks whether a given number is prime or not by looping from 2 to the number itself and checking for divisibility. If it finds any number that divides, it returns `False`, meaning the number is not a prime number.

Then we define another function which takes a dictionary as a parameter. It goes through each key-value pair of the dictionary. If the value (integer) associated with a key is prime (checked using `is_prime` function), it prints the key.

At the end of the code, we define a dictionary and call the `display_prime_keys` function using that dictionary as an input. The output would be each key that has a prime number value.


Instruction: Develop a deep learning model that can identify the tone and emotional intensity of a voice clip and provide a confidence score. Make the model robust to slight ambient noise. Voice clip: "I absolutely loved the movie"

Output:
There are some parts of the problem which are quite complex and beyond the capabilities of this platform. However, I can give you a rough guide on how to approach this problem by breaking it down into smaller steps:

1. Pre-processing Stage:
The input 'voice-clip' needs to be pre-processed for training. We can convert it into a spectrogram using tools like Librosa. This way, we get a 2D representation of the audio which we can then feed to our model.

2. Tone and Emotional Intensity:
For extracting the tone and emotion, we need a Deep Learning model. There are several pre-existing datasets containing various emotions which we can use to train the model.
The model needs to be a combination of Convolutional Neural Network (CNN) for processing the 2D spectrogram, and Long Short-Term Memory (LSTM) network, useful for extracting the temporal information in the voice-clip.

Here is a sample model in python using Keras:
```python
from keras.models import Sequential
from keras.layers import LSTM, Dense, Dropout, Masking, Conv2D, MaxPooling2D, Flatten

model = Sequential()

model.add(Conv2D(32, (5,5), activation='relu', input_shape=(128, 128, 1)))
model.add(MaxPooling2D((2, 2)))
model.add(Conv2D(64, (3, 3), activation='relu'))
model.add(MaxPooling2D((2, 2)))
model.add(Conv2D(64, (3, 3), activation='relu'))
model.add(MaxPooling2D((2, 2)))

model.add(Flatten())
model.add(Dense(64, activation='relu'))
model.add(Dense(32, activation='relu'))
model.add(Dense(10, activation='softmax'))  # Output layer.
```

3. Background Noise Rejection:
To make the model robust against background noise, we can use techniques like noise reduction, noise masking etc., during the pre-processing stage. The librosa library contains functions like power_to_db that can help in reducing noise.

4. Confidence Score:
The output of the softmax layer in the network actually represents the confidence score of each category. It outputs the probabilities of each category, making it the equivalent of the confidence score.

These are complex tasks and typically would not be undertaken by a beginner. If you are new to Python or Machine Learning, I highly recommend strengthening your understanding of these areas prior to attempting such a project.


Instruction:
Proceed with executing the following Python code, observe the process thoroughly throughout its execution, and subsequently provide a detailed analysis of the resulting output.
def string_compressor(string):
    length = len(string)
    compressed = ""
    count = 1
    i = 1
    while i < length:
        if string[i] == string[i - 1]:
            count += 1
        else:
            compressed = compressed + string[i - 1] + str(count)
            count = 1
        i += 1
    compressed = compressed + string[i - 1] + str(count)
    return compressed
print(string_compressor("aabcccccaaa"))

Output:
The given Python function `string_compressor` performs a basic form of data compression by counting the number of consecutive similar characters in a string. This is also known as Run Length Encoding (RLE), a simple form of string compression where sequences of repeated characters are replaced with one copy of that character followed by the number of times the character is repeated.

On running the code with input `"aabcccccaaa"`, the function will output `"a2b1c5a3"` after processing the whole string.

The first character it processes is 'a'. This character is repeated twice, thus 'a' is concatenated with '2'.

Next is the character 'b' which is repeated only once, hence 'b1' is appended.

After 'b', 'c' is repeated five times and thus 'c5' is concatenated.

And finally, 'a' is repeated three times at the end of the string, resulting in 'a3'.

Hence, the final compressed string becomes `"a2b1c5a3"`.

This kind of string compression is beneficial when you have a string with many repeating characters and you want to store or send it in a more compact form. However, it might not be beneficial if the string has few repeating characters, as the resulting compressed string could be longer than the original.

Please make sure that the function does not handle empty strings appropriately. It would append an artificial `"[last_character]1"` to the compressed string that didn't actually exist in the input string. To fix this, you should insert a condition to check if the input string is empty at the beginning of the function.
