Tomorrow, in March 15, 2017 at 18:05 MSK a regular rated Codeforces round for participants from the second division will take place. As usual, participants from the first division can take part out of competition. It's my second contest and I hope you'll like it more than my previous one.
As usual, there will be five problems on the contest and two hours to solve them. I advice you to read all the problems' statements attentively. Also check all your solutions for correctness even if they passed all the pretests. Verdict Pretests passed doesn't mean that the solution is completely correct! I wish you to enjoy the contest and learn something new solving the problems.
Like in the last time, the problems will be about Anton and his friends.
Great thanks to Alexey Vistyazh (netman) for help in preparing the contest, Vladislav Vishnevsky (Vladik) for testing the round, Dmitry Klebanov (dakdima) for reading the statements carefully, and of course, Mike Mirzayanov (MikeMirzayanov) for the great platforms Codeforces and Polygon.
