Recursion with Numbers

While most of the recursion we've been doing has used lists as the structure to recurse over, you can recurse with many different kinds of values.

It is fairly common to recurse using numbers.

The natural base cases for integers are when you hit 0 or when you hit 1.

The natural parameter for recursive procedure calls typically involves subtracting 1 from the argument.
