practice programs

Abdel Rahman suggested that we use the ACM problem archive and try
solving the stuff in Java.

Here's the URL: http://acm.uva.es/problemset/
You scroll down to the blue boxes, click on a Volume and then you'll
get this long list of programs you can solve.
I don't know if they're ordered in some kind of order. I'm guessing
they're not.
I also don't think we should start solving all of these like crazy.
Actually I was first thinking of goign through the 106 stuff and doing
everything in Java but this ACM thing isn't such a bad idea.
