- Write a function called mutate_list() that takes a 2D-list of integers as the input parameter and performs the following mutations: a. any even integer (non-zero) gets divided by 2, b. any odd integer less than 10 gets multiplied by 10, and c. any row (an element of the 2D-list) with less than 5 elements should be padded with zeroes to exactly 5 elements. Sample run, >>> print( mutate_list( [ [1, 2, 3], [20, 3, 40, 5, 60] ] ) ) [[10, 1, 30, 0, 0], [20, 30, 40, 50, 60]] >>> print( mutate_list( [[8,5,7,2],[13,12,9,17,5],[10,20],[1,2,3,4,5,6]] ) ) [[4, 50, 70, 1, 0], [13, 6, 90, 17, 50], [5, 10, 0, 0, 0], [10, 1, 30, 2, 50, 3]]arrow_forwardWrite a function named merge-sort in Scheme that takes a list of integers as input and returns a sorted list. (Hint: Use the merge and split-list methods that you just wrote. You will have to cut-and-paste the code into your answer.) For example, (merge-sort '(5 3 1 2 4)) should return '(1 2 3 4 5) • (every-other '()) should return '()arrow_forwardPlease 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.arrow_forward
- Write a program in python with a function isPal(L), where L is a list of integers, and the function returns True if the list is a palindrome, False otherwise. For example [5, 2, 9, 9, 2 5] is a palindrome. Use the reverse() method of list and check if the reversed list is the same as the original list.arrow_forwardExercise G -- Implement a function halves that takes a list of integers and divides each element of the list by two (using the integer division operator //) NOTE use the map function combined with a lambda expression to do the division with a neat solution halves : List Int -> List Int halves xs = [ ] --remove this line and implement your halves function herearrow_forwardWrite a function swap that swaps the first and last elements of a list argument. Sample output with input: 'all,good,things,must,end, here' ['here', 'good', 'things', 'must', 'end', 'all'] Learn how our autograder works 4517103116374.qx3zqy7 1 2 Your solution goes here 3 4 values_list = input().split(',') # Program receives comma-separated values like 5,4,12,19 5 swap(values_list) 6 7 print(values_list) 111arrow_forward
- Implement a function findMixedCase in Python that: accepts a single argument, a list of words, and returns the index of the first mixed case word in the list, if one exists, (a word is mixed case if it contains both upper and lower case letters), and returns -1 if the all words are either upper or lower case. sample: >> findMixedCase( ['Hello','how','are','you'] ) # 'Hello' is mixed case0arrow_forwardWrite a version of the sequential search algorithm that can be used to search a sorted list. Write a program to test the sequential search algorithm. Use either the function bubbleSort or insertionSort to sort the list before the search. Your program should prompt the user to enter 10 digits and then prompt the user to enter a digit to search - if the list contains this digit, output its position to the console: x is found at position y If the digit is not contained in the list, output the following: x is not in the listarrow_forward
