The anniversary Codeforces Round #200 is scheduled to take place today at 7:30 PM Moscow time. The round will be held in both divisions and will be rated.
The round problems were prepared by Evgeny Vihrov (gen), Andrey Vihrov (andreyv) and Gerald Agapov (Gerald). As always, we would like to thank Mike Mirzayanov (MikeMirzayanov) for the Codeforces and Polygon systems, and also Maria Belova (Delinur) for translating the problem statements.
In this round you will help mad scientist Mike to realise his peculiar ideas and carry out unusual experiments. The authors think that the problems constitute a good balance between mathematics and programming. We also tried to make the statements short and easy to read :] As always, we hope that every participant will find a problem to his taste.
We wish you good luck and an interesting round!
