Project Euler

[Sanket Patel]

I just ran across this website - Project Euler - which contains over 200 programming problems. They range in difficulty from simply finding the (n^{th}) prime number to finding Minkowski sums.

If you're looking to brush up on programming or perhaps explore a new language, Project Euler is a nice way to relax on those Saturday nights when all you want to do do is write some algorithms.

Another good resource is the ACM programming competition problem archive. Each problem set has about 8 problems and the time alloted is about 5 hours. I found it exremely helpful for interview preparation/ skills consolidation by doing progamming marathons with couple of buddies
