thanks man! really nice thing..will keep me busy for the next few days..

I did 61 problems early in the summer in a couple weeks.

I just started doing it, the ones I have done are pretty easy. I'm only through the first 15 though.

wow definitely a challenge, thanks for sharing this site

I've seen this already. Some can be done with pencil and paper Math.

I usually try this out but I usually end up doing brute force methods. Maybe it should have some solution page (does it)?

I think project euler doesn't, Google Code Jam shows every solution uploaded (meaning the source code). Don't remember about the other sites, but there are forums to discuss your solution with other people.

I think all of the sites I posted, unlike Project Euler, have a time limit for you solution. In Google Code Jam you only have 4 minutes, I think, and I believe uva compiles your source code and runs it for a test input, so it's probably around a couple of minutes. A brute force approach will, most probably, fail to give an answer within those time constraints.

Some problems take some time to get solved, but most are easily solved with variations of classical algorithms in graphs if you model your problem adequately.

I've done the first ten and a few random ones after that. Good way to relax and do something puzzling that isn't so stupid as a crossword.

Been doing this for a while now. Pretty interesting puzzles and an excellent way to learn some algorithms/data structures as you do it.

I tried projecteuler a while back but I didn't get too far. I'll have to check out the python challenge since python is my main programing language (not counting web languages). These kinds of games can help improve my problem skills which are always helpful especially in my field of study.

ooh. math is always awesome when programming
