Write a Python function round_up that, given an integer, rounds it up the next multiple of 100. If the given number is already a multiple of 100, it is just returned.  For example,  round_up(234) returns 300  round_up(465) returns 500 round_up(400) returns 400 The round_up function does not read input or print output.

Write a python program with the following functions:1. the function factorial_loop(num) that takes an integer num and returns the value of the factorial of num written as num!, where num! = num * (num-1) * (num-2) * … * 2 * 1. This function must use a loop (iteration) to compute the value of num!.2. the function factorial_recursive(num) that takes an integer num and returns the value of the factorial of num (i.e., num!) as defined above. This function must use a recursive algorithm to compute the value of num!.

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.
