The round consists of 6 problems and you will have two hours to solve them.
The problems were prepared by me with great help from linkinu and 1am. I would like to thank KAN for his great efforts in reviewing the problems and for his suggestions, it is really amazing to see the work done behind every round. Also thanks to Tommyr7, Livace and mike_live for testing the problems, and to arsor for translating the statements into Russian.
This is my first round on Codeforces, I hope that you will find some interesting problems for you.
Note that the round is rated for everyone with rating below 2100.
Good luck and have fun!
UPD: Congratulations to the winners:
