The regional level of the ACM ICPC coding contest is just around the corner. Are you ready for the challenge? To help you in preparing for this prestigious coding contest, we've set up a practice challenge for you.

The format of the contest is styled to be exactly similar to the ACM ICPC contests - the teams are given 5 hours to solve between 8 and 12 programming problems. You must submit solutions as programs in C, C++, or Java. Programs are then run on test cases. If a program fails to give a correct answer, you must submit another program. The winner is the team which correctly solves most problems in the shortest span of time.

So, gather your team, and participate to be prepared for the most prestigious programming competition in the world!
