I know that the proper way to do it is with recursion. I shouldn't 
have called it unconventional though, sorry. Its just an exercise I can't 
solve. I've read in some tutorial it can be done using loops but it didn't 
give any examples and I can't figure it out on my own. I was hoping 
someone could at least give me a hint.
