Me - Sergey Vedernikov - is the author of today's CF beta round.
During the round you'll assist far away kingdom citizens in solving everyday problems, and sometimes - just to fight for your survival.
This round is "red" =), therefore the problems should not appear too difficult, and you should get pleasure from solving them.
To those who know Russian language I recommend to read problem statements in Russian. Not because of the quality of translation - English just poorly communicates Russian folklore language style.
Finally I want to thank Artem Rakhov for invaluable help during the round preparation, Maria Belova for the qualitative translation of the problems, Mikhail Mirzayanov for excellent CF system and all participants for not leaving this event without your attention.
More AC verdicts and high rating to all of you! gl & hf
UPD: Unfortunately, problem B (div. 1) / D (div. 2) appeared to be more difficult, and author's solution appeared wrong. The round will be unrated. I apologise for this to all participants.
