Recursive Loop

While looping is great, it's not the only way to iterate. In fact, looping is frowned upon in Functional Programming. A functional language such as Haskell doesn't even have loops! It might be hard to believe, but you don't really need loops if you have recursion.

This challenge will give you a taste of what life would be like without loops.

Requirements

1. Write a function that takes an integer. The function should print all the integers from 0 to the integer.
2. Same thing, but count down to 0.
