Welcome all to Codeforces Beta Round #22
Note that at this time registration is possible during the round. The contest will begin at 19:00 MSK.
Today I am an author of the problems. I would like to thank Mike Mirzayanov for help in contest preparations, Edvard Davtyan and Nickolay Kuznetsov for writing the verification solutions, and Julia Satushina for translating statements into English.
Good luck on the contest!
UPD: The contest is over. Thank you all for participating!
Winner Kasparyanm_Mihail gains +203 to rating after the contest!
Thanks in advance,

I hope they do something about this in future!

Thanks in advance!

I'm Chinese. Believe me ..........
