[Contest] Statement Not Found: Season 2

Revision en4, by zscoder, 2022-08-28 17:11:02

Do you think you can solve CP problems without reading the problem statements? Let's find out!

On August 28, 2022 (Sunday) 19:30-22:00 GMT+8, I will hold an unofficial fun contest called Statement Not Found. As you can deduce from the title, there will be no problem statements (except title and samples). Your goal is to collect as many points as possible within 2.5 hours :)

Obviously, this round is unrated. It is somewhere between April Fools contest and a legitimate contest.

The contest will be OI-style, meaning there will be no time penalty. You are allowed to use any resources online to help solve the problems. There will be 12 problems.

Scoring Distribution: 200-400-700-700-700-800-800-900-1100-1100-1100-1500 (Total: 10000)

Please read all problems as problem difficulty is very subjective and a 1100-point problem might be easy for you while a 700-point problem might be difficult. The last problem is meant to be a tiebreaker.

You can participate solo or in teams of up to 3 (I would allow more team members but apparently Codeforces doesn't support it). Teams are highly recommended if you intend to solve everything in 2.5 hours. Good luck and have fun!
