Question
Please 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. Please do not use a triply nested loop, use the properties of a pythagorean quadruple to write the function.

Follow-up Question
The code should print quadruples (x,y,z,w) such that x^2 + y^2 + z^2 = w^2. The outputs given do not do this.

- Write the python function selection_sort_descend_trace() that takes an integer list and sorts the list into descending order. The function should use nested loops and output the list after each iteration of the outer loop, thus outputting the list N-1 times (where N is the size). Complete __main__ to read in a list of integers, and then call selection_sort_descend_trace() to sort the list. Ex: If the input is: 20 10 30 40 then the output is: 40 10 30 20 40 30 10 20 40 30 20 10 I have a whitespace error. I need to have a space after the last index position prints but I can't seem to get the space in without either adding a new line. what can i do to fix this?arrow_forwardQuestion: First write a function mulByDigit :: Int -> BigInt -> BigInt which takes an integer digit and a big integer, and returns the big integer list which is the result of multiplying the big integer with the digit. You should get the following behavior: ghci> mulByDigit 9 [9,9,9,9] [8,9,9,9,1] Your implementation should not be recursive. Now, using mulByDigit, fill in the implementation of bigMul :: BigInt -> BigInt -> BigInt Again, you have to fill in implementations for f , base , args only. Once you are done, you should get the following behavior at the prompt: ghci> bigMul [9,9,9,9] [9,9,9,9] [9,9,9,8,0,0,0,1] ghci> bigMul [9,9,9,9,9] [9,9,9,9,9] [9,9,9,9,8,0,0,0,0,1] ghci> bigMul [4,3,7,2] [1,6,3,2,9] [7,1,3,9,0,3,8,8] ghci> bigMul [9,9,9,9] [0] [] Your implementation should not be recursive.

The function is supposed to take a single integer parameter. It indicates the maximum value of Fibonacci numbers that will be in the list and it uses recursion to generate the list. fibList n = go n 1 1 where go n f s | (f+s) > n = [] | otherwise = (f+s) : go n s (f+s)arrow_forward

- Please I need it quickly !!! In python We have a list (named data) of numbers sorted in ascending order, for example: data = [2, 4, 5, 9, 10, 12, 13, 17, 18, 20] Write a function (named DataVar(data)), which take a list (data) as input parameter and performs the following steps on the list: 1) it finds the mean m of the data (for the given example, it is m = (2 + 4 + 5 + 9 + 10 + 12 + 13 + 17 + 18 + 20)/10 =110/10 = 11). 2) then, it finds the difference of data and m. Essentially, it finds for all data: Diff = data-m For the given example, Diff = [-9, -7, -6, -2, -1, 1, 2, 6, 7, 9]. 3) then, it finds the sum of Diff and 7. Essentially, it finds for all data: Sums = Diff+7 For the given example, Sums = [-2, 0, 1, 5, 6, 8, 9, 13, 14, 16]. 4) then, it finds the square of all the elements of Sums, such that Squares = square of the elements of Sums. For the given example, Squares = [4, 0, 1, 25, 36, 64, 81, 169, 196, 256]. 5) it finds the average of Squares and stores it in result, and…arrow_forwardThis is for Python version 3.8.5 and please include pseudocode. nums = [8, 15, 6, 17, 33, 20, 14, 9, 12]Write Python code that: uses a function to print the size of the list named nums uses a function to print the largest number in nums prints the element 14 by using its index makes a slice named subnums containing only 33, 20, and 14arrow_forwardUse Python when answering the question: Write a function primeFac that computes the prime factorization of anumber: it accepts a single argument, an integer greater than 1 it returns a list containing the prime factorization each number in the list is a prime number greater than 1 the product of the numbers in the list is the original number the factors are listed in non-decreasing order Output is in the attached picture:arrow_forward
