Very soon on 13 october at 19:30 MSK will take place Codeforces Round #206. I am author of the problems and it's my first round!
I would like to thank problem coordinator Gerald Agapov (Gerald), Evgeny Vihrov (gen) for problem testing and Mary Belova (Delinur) for translation of statements to English. Special thanks to Michael Mirzayanov (MikeMirzayanov) for marvelous Codeforces and Polygon systems.
Score distribution will be standard in both divisions: 500-1000-1500-2000-2500.
I wish good luck for everyone and hope that you will enjoy the problems!
Congratulations to the winners! Special congratulations to rng_58, the only participant, who have solved all 5 problems!
