I added one interesting team contest for preparing ICPC World Final into gym!
Every year National Taiwan University will host selection contest in order to determine which team will go to World Final. This year, I host this contest. Ideas of most problems are came from me. Hope these problems can let everyone feel interesting!
I set the start time of this contest as 13:30 UTC. If you have no time in this time slot, don't be sad. You still can choose any time after that to enjoy the contest.
UPD: Reminder : The contest will start in around 6 hours from now.
