I just stumbled upon this this cool website : http://projecteuler.net

They offer a ton of math problems that require good knowledge of maths and programming. For every 25 problems you solve, you level up, and there's some talk of prizes as well (not sure, I just started).

Make sure to check it out if you feel you're not challenged enough at school / work.

I tried to click on the link, but my 11 fingers just aren't very good at using the mouse properly.

I, too, started participating in this at the beginning of the school year after I got linked to it on the devhat IRC. Most of the problems I've encountered involve being solved with dynamic programming.

That's odd... My compiler won't accept this (C++):

__int64 number = 600851475143;

I have to do this:

__int64 number;
number = 6008514;
number = number * 100000;
number = number + 75143;

Works for me with long long.

EDIT: Just tested it with __int64 and it worked fine.

You might have to put "LL" after it. That's part of C99 though, so it may not work for all compilers.

Thats what I found out about java too. Unless there's an 'L' at the end the compiler tries to read literals as integers.

Also I solved the top 2 Problems, was too lazy to find a nice solution for the third
But it looks like a nice prgramming/logical/mathematical practice.
