Testers are Liao Ninglin, Zou leqi, Huang Yicheng, Hu Tianxiang, Chen Hao, Chen Ming. We express our thanks to them!

The contest will be scored as an ACM/ICPC contest. So every problem matters equally.

The difficulty of problems in this contest will vary largely from the easiest to the hardest. We tried to adjust the difficulty of the problems in order to match the skills of the majority. There won't be problems way too hard, so we expect some full score contestants.

This is our first POJ challenge Contest round, I hope you can enjoy it. Wish you good luck! And don't forget to tell people around you so they can know this contest.
