Hi Agnishom and anonimnystefy;

I would suggest Project Euler and Nick's puzzles for the both of you.

**I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.**

I alredy know project Euler. A very cool site. Combines math and programming very nicely.

And I'll suggest codechef

A good site as well. There is also Top Coders.

Also, visit gowrikumar for some nice C/C++ puzzles and rinkworks.com/stupid for computer (and programming) stupidities.

I am too late to visit this thread back, but I have already tried Project Euler

Nick's is interesting...

Hi Agnishom;

Nick's will keep you busy for awhile.

Nick's is quite tough.

Hi Agnishom;

I have never even looked at it. My preferences are towards combinatorics, probability and numeric computation.

Hi Agnishom

Note that the problem he would recommend to you might not be a problem he would work on.
