Hello everyone. I'm Mikhail Tikhomirov and I'm the author of today round. I want to say big thanks to Gerald Agapov (Gerald) and Artem Rakhov (RAD) for great help in preparing this contest, and also Maria Belova for translating the statements into English (Delinur).
Today round is for contestants from both divisions. Each division has five problems, which intersect, as always. Score distributions are also standard (500-1000-1500-2000-2500). In short, it's a usual round. Or not?.. =)
Hope that problems will be interesting, tests will be secure, server will be fast, solutions — (mostly) correct, and the round will be rated. =) Wish you best of luck!
Round finished, thank you all for participating!
Editorial is finally up!
