Write a recursive function named multiply that takes two positive integers as parameters and returns the product of those
two numbers (the result from multiplying them together). Your program should not use multiplication - it should find the
result by using only addition. To get your thinking on the right track:
7 * 4 = 7 + (7 * 3)
7 * 3 = 7 + (7 * 2)
7 * 2 = 7 + (7 * 1)
7 * 1 = 7
So, 7 * 4 = 7 + (7 + (7 + (7)))
Your code must not contain any loops.
The file must be named: multiply.py
