My name is Danil Sagunov, and I used to be red... Anyway, I wish to congratulate you with the Second Revolution!
I am glad to introduce that this Saturday, 3rd October at 19:30 MSK Codeforces Round #323 for both divisions will take place. Problemset has been prepared for you by me and Vitaly gridnevvvit Gridnev. This is not the first round we are authors of and I'm sure that it's not the last.
Special thanks to our friends Maxim Ne0n25 Mescheryakov, Vladimir P1kachu Petrov and Roman luigi_vampa Glazov for helping us preparing the round. I would like to thank Max Zlobober Akhmedov for his coordinator activity, Michael MikeMirzayanov Mirzayanov for creating and supporting Codeforces and Polygon systems, making this round possible, and Maria Delinur Belova for translating problem statements into English.
Both division participants will be given five problems and two hours to solve them. I hope that everyone will find the problems interesting and many of you will return your colors.
UPD The round duration was written incorrectly in the e-mail announcement, the correct duration is 2 hours, not 2.5 hours.
UPD2 Round have been successfully finished! Thank you all for participating.
Congratulations to 1 division winners!
And the second division:
My gratitude to foti1e96, one to solve problem D!
