Hi! Soon Codeforces Round #220 (Div. 2) will take place, i am the author, Dmytro Berezin. This is my third round and Sereja still hopes, that this is the last :)
Everything changed since last round. Dima and Inna have thought about their behavior and asked Sereja to excuse them. They are good friends now. You should make the family happiness even stronger!
Thanks to Gerald Agapov (Gerald) for the help in round preparation, Maria Belova (Delinur) for tasks translations, Mike Mirzayanov (MikeMirzayanov) for perfect system, and Sergii Nagin (Sereja) for his agreement (not to post here another photo) to help in testing.
Points distribution will be. 500-1000-1500-2000-2500. Here we go :)
