Write a recursive C++ function, sumdigits, which will accept a positive integer and calculate and return the sum of the digits in the number. For example, if 123456 is passed to this function, it would return 1+2+3+4+5+6 = 21. Requirements and Comments: The sumdigits function must not contain any cout or cin statements. • The sumdigits function must be recursive. You do not need to write a complete program.

When the following program is executed, it terminates with an error. Which option best describes the cause of this error? Question options: The function will terminate the program due to the recursive limit being reached. The function will terminate the program due to a type mismatch when evaluating an operator. The function will terminate the program due to invalid syntax. The function will terminate the program due to an invalid type conversion. The function will terminate the program due to it accessing an invalid list index. None of these options

Objective: Practice writing recursive functions in python3 Make the five recursive functions described below in python3 by using the starter code recursive_functions.py. For each function, figure out how to solve it conceptually : write down the base case (when recursion stops) and how each recursive function-call moves towards the base case. The functions should not print anything (except you may add temporary print statements to help debug them). You can test your program by using the provided program test_recursive_functions.py. Don't edit the test program. Put it into the same directory (folder) with your recursive_functions.py and run it. It will import your functions as a module, test your functions, and tell you when each function is returning correct results. 1. Factorial In math, if you have a number n, the factorial function (written n!) computes n x (n-1) x (n-2) x (n-3) x ... x 1. For example: 0! is defined to be 1 1! = 1 2! = 2 x 1=2 3! = 3 x 2 x 1=6 4! = 4 x 3...

program in C++ with the name, towers.cpp which helps to solve the Towers of Hanoi puzzle using this recursive approach. The main() routine should make a single call to the recursive member function do Towers(). This function then calls itself recursively until the puzzle is solved. Note: solve as soon as possible
