    1. Recursion is ususally where a function calls itself; (another example of recursion is where function A calls function B, and B calls C and C calls A, creating a loop in the calls). Some problems are most naturally solved recursively, such as writing the factorial function, or finding all the perumutations of a sequence, or checking if a string is a palindrome. Since those examples were done in class, here we will give you a toy example, which normally...

    PYTHON 3.6 (Short and Simple Codes Please) Write a recursive function, reverse, that accepts a parameter containing a string value and returns the original string in reverse. For example, calling reverse('goodbye') would return 'eybdoog'. Reversing a string involves: No action if the string is empty or only has 1 character Concatenating the last character with the result of reversing the string consisting of the second through next-to-last character, followed by the first character

    Write a recursive function in Python to find the sum of digits of a number. Name the function sum_of_digits. The function should use recursive algorithm (calling itself). The function should print out the sum of all the digits of a given number. For example, sum_of_digits(343) should have a output of 10. Marks will be deducted if you do not follow strictly to the instructions. [3]: N 1 def sum_of_digits(n): HNM in sum_of_digits (343) Out[3]: 10

    C++ Assignment 4 - For example 2, write a non recursive version of this function... using a regular loop. Let's consider writing a function to find the factorial of an integer, N!. For example 7! equals 7*6*5*4*3*2*1. int myFactorial( int integer) if( integer == 1) return 1; else return (integer * (myFactorial (integer-1))); // action performed on call - pass into function "integer - 1" // action performed on return *
