The problems are prepared by me(Sadegh Mahdavi) and MaGaroo(Majid GarooC). Great thanks to Arpa(AmirReza PoorAkhavan) and Livace(Alexey Ilyukhov) for testing the round, KAN(Nikolay Kalinin) for helping us preparing the round and MikeMirzayanov(Mike Mirzayanov) for the Codeforces and Polygon systems.
There will be 5 problems and 2 hours to solve. The scoring will be published later.
The main characters of this round are chosen from the game of thrones series :D
UPD : The scoring is : 500 — 1000 — 1500 — 2000 — 2500
UPD: The judges solutions for problem B incorrectly handled some case, so we are going to rejudge some of the hacks. The pretests are not affected, so the contest is going to be rated.
UPD : The round is finished. Congratulations to winners:
