Competitive programming is fun :)
I've competed in several algorithmic programming competitions over the past few years; below are a few of the major ones:
- USA Computing Olympiad (USACO)
- Facebook Hacker Cup
- Google CodeJam/KickStart
- ACM Intercollegiate Programming Contest (ICPC)
- 15-295 (CMU's Competitive Programming Class/Club)
Here are my solutions to problems from several of them (as well as a few templates I use), all are in C++. Also, every solution here is complete.
