Exercise 02 The call list (someString) transforms a string into a list of characters. Write the following function: def printAsString (a_listString) where a listString is a word that has been transformed into a list using the list () function. The function should print the list as a word. For example, if the list is ['h', 'e', '1', '1', 'o' ], the function should print hello. The function does not return anything. Test the function after writing it.
python lab Write a recursive function named reverse that accepts a string argument and returns the original string with its characters reversed. For example, calling reverse ('goodbye') would return 'eybdoog'. The function must use recursion to reverse the characters in the string. Do not use a loop.
Write a recursive function that returns the largest integer in a list. Write a test program that prompts the user to enter a list of integers and displays the largest element.
Write a recursive Python function named initList to create a list containing the values from 0 to n-1. • The function takes two parameters, a reference to the list and an integer which is the value n. In the main program you must: - initialize a list (L = []) - call the recursive function initList with this list L, to modify it - and, ask the user to enter the value n from the keyboard
Construct recursive versions of the library functions that: a. calculate the "sum" of a list of numbers. b. "take" a given number of elements from the beginning of a list. c. select the "last" element of a non-empty list .
How would I write double_str and double_list using only recursion functions?
Calculation "a" was used for loop to calculate the sum of squares of values in this list: 1, 7, 8, 6, 11 (The answer was 271) (Question 1) Create recursive function to do the same calculation "a" in the above. (The function input will be the list. Each recursion, you are going to send a sub-list with one less item from the list) (Hint:There are many ways to do sorting. Create a function to perform bubble sorting as descried in this tutorial: (https://www.geeksforgeeks.org/bubble-sort/) . The algorithm should stop when there are no swaps in the last iteration.)
Code the following in OCaml. EDIT: Write a function that looks for a pair on elements from two integer lists that sum to a given value. Note: Only use recursion and lists. You may need a auxiliary or helper function. Write the following function sumOfTwo (a, b, v) that returns true if there exists an integer a list that when added to any integer in a different list, equals the sum. Signature: val sumOfTwo : int list * int list * int -> bool = Example output: # sumOfTwo([1;2;3],[10;20;30;40],42);; :bool = true (since 2 + 40 = 42) # sumOfTwo([1;2;3],[10;20;30;40],40);; :bool = false (nothing in list 1 can be added to list 2 to get 40)
Quick Sort We choose an element from the list, called the pivot. We'll use it to divide the list into two sub-lists. We reorder all the elements around the pivot The ones with smaller value are placed before it All the elements greater than the pivot after it. After this step, the pivot is in its final position. This is the important partition step. We apply the above steps recursively to both sub-lists on the left and right of the pivot. Quick Sort (Example) Consider the following array Arr[] = {5, 9, 4, 6, 5, 3} Let's suppose we pick 5 as the pivot for simplicity We'll first put all elements less than 5 in the first position of the array: {3, 4, 5, 6, 5, 9} We'll then repeat it for the left sub-array {3,4}, taking 3 as the pivot There are no elements less than 3 We apply quicksort on the sub-array in the right of the pivot, i.e. {4} This sub-array consists of only one sorted element We continue with the right part of the original array, {6, 5, 9} until we get the final ordered…
