Imagine that suddenly all machines have gone insane and simple multiplication is not working for natural numbers anymore. Let's write a new function for this task recursively!
It's known that "a times b" is the same thing as "a plus itself b times". So we can rewrite the expression in the following way:
We need to reduce this problem to a smaller one with the recursive step, and then stop recursion with the base step.
Modify the template code below into a working function that takes two positive integers as its input and returns their product.
