Hey All,

I just finished my code and it seams to work fine. I'm looking for advice on improving it or making it easier to understand. Its not Fully complete because I only have to set up to take in a number less than 2147483648 because i am using an int. I know that can be changed, but before I get it fully polished I would appreciate your insights.

Thanks for Reading

Nathan
