- Write a recursive function that parses a hex number as a string into a decimal integer. The function header is as follows:def hexToDecimal(hexString):Write a test program that prompts the user to enter a hex string and displays its decimal equivalent.arrow_forwardObjective: 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...arrow_forwardWhich of the following is false? A) Problems that cannot be solved using loops can be solved with recursive functions B) Recursive functions have a recursive case that does work and then calls the function again. They also have a base case that solves the most basic instance of the problem. C) It only makes sense to use recursive functions to solve problems with integer answers. D) Upon execution of a recursive function, python stores different instances of the function's local variables and arguments for each recursion call.arrow_forward
- language: Python Problem: Write a recursive function to add a positive integer b to another number a, add(a, b), where only the unit 1 can be added, For example add(5, 9) will return 14. When creating the function, also create a test case to prove the program works. The pseudocode is: # Base case: if b is 1, you can just return a + 1# General case: otherwise, return the sum of 1 and what is returned by adding a and b - 1arrow_forwardWrite code to complete raise_to_power().
