- Lab Goal : This lab was designed to teach you more about recursion. Lab Description : Take a number and recursively determine how many of its digits are even. Return the count of the even digits in each number. % might prove useful to take the number apart digit by digit Sample Data : 453211145322224532714246813579 Sample Output : 23540arrow_forwardPython Using recursion only No loops Note that in a correct solution the isdigit method or in operator will never be applied to the entire string s. The function must return and not print the resulting string. def getDigits(s):arrow_forwardInstructions : Complete the tasks listed below. ask Lists Complete the body for the recursive method fac(n) which computes n! (n factorial) for n >= 0. Note: n! = n(n - 1) (n - 2) (n - 2)… (2) (1), where n > 0 and zero factorial, 0! = 1. Complete the body for the recursive method sum(n) to compute the sum of the first n positive integers. Complete the body for the recursive method pow(x,n) for computing xn, for a positive integer n, and real number x. Complete the body for the recursive method isPalindrome(str) to determine if a string of text is a palindrome. This method accepts a String and returns true if the string reads the same forwards as backwards. The string is trivially true for empty or one(1) letter strings.

- (Towers of Hanoi: Iterative Solution) Any program that can be implemented recursivelycan be implemented iteratively, although sometimes with considerably more difficulty and considerably less clarity. Try writing an iterative version of the Towers of Hanoi. If you succeed, compareyour iterative version with the recursive version you developed in Exercise 5.36. Investigate issuesof performance, clarity, and your ability to demonstrate the correctness of the programs.arrow_forwardIteration versus one-friend recursion. 1. Your job is to accept the tuple a1, a2,..., a and return the tuple an, an1,..., a1 that has been reversed. You will only take an element off of one end or put an element back on one end because you are being indolent. But you have allies in recursion who can assist you.Please include the recursive code as well as a paragraph with the friend's description of the algorithm. 2. Now imagine that you lack pals but have a stack. (Refer to Chapter 3. Quickly design an incremental programme to address this issue. Include loop invariants and other crucial stages that are necessary to describe an iterative algorithm. 3. Trace both of these scripts separately. Compare and contrast their computerised calculations step by step.arrow_forwardJava programming language Write a recursion method to sum the odd numbers a) from 100 to 0 b) from 0 to 100 and then test it.arrow_forward
