The round will consist of 6 problems and you will be given two hours to solve them.
Task prepared by me, den2204.
Thanks MikeMirzayanov for the platform Codeforces, KAN for round coordination and help with preparation. Thanks gritukan, Andreikkaa, flyrise, Um_nik, Aleks5d and osaaateiasavtnl. for help with preparation and testing round, arsor for translating statements into English, arsijo for assistance in conducting the round. Thanks Andreikkaa for the idea of the problem E.
P.S. It is my first round on Codeforces, please, do not judge strictly :)
UPD: Added editorial. Thank you all for participating and for the feedback on the contest. I apologize for the leap in complexity between tasks and for weak pretests for some tasks, I’ll take this into account when further preparing contests.
