算法解题比赛

http://github.com/ealmansi/misc-programming-problems
I participated three times in the ACM International Collegiate Programming Contest, an annual multi-tiered competitive programming competition among the world's universities.

For this competition, candidates must train themselves to master advanced data structures and algorithms and the skill of coding bug-free programs under pressure and tight time constraints. The attached code sample is a solution I wrote for a competitive programming problem from the Sphere Online Judge (SPOJ).

Note: The code is optimized for execution speed and minimizing coding time as is required in such competitions, not legibility.
