We would also like to thank several volunteers who made this programming contest possible. VSoE made the labs available for the contest, and provided competent technical support. Marcos Vieira, Kai Song, and Akshat Gupta developed sample solutions and helped as contest judges. The ACM student chapter provided volunteers for contest setup, checkin, technical help, food, and other aspects of the contest.
