Greetings to the Codeforces community!
Regular Codeforces round #316 for participants from the second division will take place on August 13, 19:30 MSK. Participants from the first division are able to participate out of the contest.
It is my first round on Codeforces. Hope you will enjoy this round.
I want to thank Max Akhmedov (Zlobober) for help with preparation of this round, Maria Belova (Delinur) for translation of statements and Mike Mirzayanov (MikeMirzayanov) for great Codeforces and Polygon systems.
Participants will be given five problems and two hours to solve these problems.
UPD: The score distribution is standard, 500-1000-1500-2000-2500
