write a function PythQuad(n) in python that generates a list of pythagorean quadruples (x,y,z,w) such that x <= y <= z <= w < n. A pythagorean quadruple states that x^2 + y^2 + z^2 = w^2. Please do not use a triply nested loop, use the properties of a pythagorean quadruple to write the function.

In c++ please help me answer this question I will give you a good rating :) implement the three versions of the addupto20() function: iterative, recursive, and divide-and-conquer approach test these functions with a few inputs from your main() Iterative solution * check if there exsits two numbers from vector data that add up to 20 e.g., if data=[2,5,3,15], the function returns true, as data [0] +data [3]==20 e.g., if data=[3,4,0,8], the function return false precondition: vector data has been initialized postcondition: if there are two numbers from list add up to 20, return true; otherwise, return false */ bool AddupTo20 (const vector‹int> & data){ } Come up with a recursive solution to the problem, following the hints given below: * check if there exsits two numbers from vector data[first...right] add up to 20 e.g., if data=[2,5,3,15], first=0, last=3, the function returns true, as data [0] +data [3]==20 e.g., if data=[2,5,3,15], first=2, last=3, the function returns…

write a c++ recursive function to solve the following: str contains a single pair of parenthesis, return a new string // made of only the parenthesis and whatever those parensthesis contain. You can use substr in this problem. // // Pseudocode Example:// findParen("abc(ghj)789") =&gt; "(ghj)" // findParen("(x)7") =&gt; "(x)" // findParen("4agh(y)") =&gt; "(y)" // string findParen(string str) { }

Initialize a vector v1 with the following values: 0 23 -7 8 -22 3 14 Write a MATLAB program from the values in v1. The vector v2 should contain the values in v1 transformed as follows: that uses a for-loop and if-statements to make a new vector v2 multiply each positive even element in v1 by 3, multiply each positive odd element of v1 by -2, and change the sign of the negative elements in v1. Then, output the new vector to the command window as follows: The new vector is: -46 7 24 22 -6 42 Also, compute and output the mean of the values in the new vector: The mean of the new vector is: xxxx Above, xxxx is the mean of the values in the new vector with 1 decimal place.

Data Structures and Algorithms in C/C++ a) Implement the addLargeNumbers function with the following prototype: void addLargeNumbers(const char *pNum1, const char *pNum2); This function should output the result of adding the two numbers passed in as strings. Here is an example call to this function with the expected output: /* Sample call to addLargeNumbers */ addLargeNumbers("592", "3784"); /* Expected output */ 4376 b)  Implement a test program that demonstrates adding at least three pairs of large numbers (numbers larger than can be represented by a long). c) (1 point) Make sure your source code is well-commented, consistently formatted, uses no magic numbers/values, follows programming best-practices, and is ANSI-compliant.

Write a function that adds two polynomials. Ensure that the polynomial produced matches the requirements in HASKELL. addPoly :: (Num a, Eq a) => Poly a -> Poly a -> Poly a For example: > addPoly (P [1]) (P [-1,1])P [0,1]> addPoly (P [17]) (P [0,0,0,1])P [17,0,0,1]>addPoly (P [1,-1]) (P [0,1])P [1] You may find it helpful to write addPoly using two helper functions: one to combine the lists of coefficients, and one to trim trailing zeroes.

I'm trying to delete a node after inputting data for 2-3 checks but the node I try to delete remains in the list. How do I fix my deleteCheck() function to run correctly with the rest of my code? Thank you. #include <stdio.h>#include <stdlib.h>// Austin Chong// The core concept of this assignment is to use a linked list in a C program.// 07 March 2020 struct checkNode{int checkNumber;char date[8];char paidTo[100];char description[100];double amount;struct checkNode *head;struct checkNode *next;}; struct checkNode *checkBook = NULL; /* Functions */ void addCheck(){int checkNumber;double amount;char temp;struct checkNode *newCheck = (struct checkNode*) malloc(sizeof(struct checkNode));printf("Please enter the check number: ");scanf("%d", &checkNumber);newCheck -> checkNumber = checkNumber;printf("Please enter the amount: ");scanf("%lf", &amount);newCheck -> amount = amount;printf("Please enter the date: ");scanf("%c", &temp);scanf("%[^\n]", newCheck ->…

Implement in C Programming 6.11.2: Modify an array parameter. Write a function SwapArrayEnds() that swaps the first and last elements of the function's array parameter. Ex: sortArray = {10, 20, 30, 40} becomes {40, 20, 30, 10}. #include <stdio.h> /* Your solution goes here  */ int main(void) {   const int SORT_ARR_SIZE = 4;   int sortArray[SORT_ARR_SIZE];   int i;   int userNum;    for (i = 0; i < SORT_ARR_SIZE; ++i) {      scanf("%d", &sortArray[i]);   }    SwapArrayEnds(sortArray, SORT_ARR_SIZE);    for (i = 0; i < SORT_ARR_SIZE; ++i) {      printf("%d ", sortArray[i]);   }   printf("\n");    return 0;}

Consider the following function:int enigma(NodeInt32* node){if(node == NULL)return 0; elsereturn 1 + enigma(node->next);}(a)The enigma function is recursive.A. True B. False

Python’s list method sort includes the keyword argument reverse, whose defaultvalue is False. The programmer can override this value to sort a list in descendingorder. Modify the selectionSort function so that it allowsthe programmer to supply this additional argument to redirect the sort. selectionSort function: def selectionSort(lyst, profiler):i = 0 while i < len(lyst) - 1:minIndex = ij = i + 1 while j < len(lyst):profiler.comparison() # Countif lyst[j] < lyst[minIndex]:minIndex = jj += 1 if minIndex != i:swap(lyst, minIndex, i, profiler)i += 1 def swap(lyst, i, j, profiler):"""Exchanges the elements at positions i and j."""profiler.exchange() # Counttemp = lyst[i]lyst[i] = lyst[j]lyst[j] = temp Use this template in Python to modify the function above: def selection_sort(input_list, reverse):sorted_list = []#TODO: Your work here# Return sorted_listreturn sorted_listif __name__ == "__main__":my_list = [1, 2, 3, 4, 5]print(selection_sort(my_list, True)) # Correct Output: [5,…
