There will be an official round for teams from VK cup, but if you are not eligible to participate in it, then you can compete (alone, not in team) in one of two additional editions (one for div.1 and one for div.2), so everybody is invited to take part in the competition! Just register in your category here. All three rounds will be rated. Div.1 and Div.2 editions will look like normal CF round, but will have common problems with official edition.
If you can't register before the round, then you will be able to do it during the contest (but not for the entire duration, you can chcek it here). Let's thank Mike for this great feature!
We want to thank GlebsHP for help in preparing the problems and MikeMirzayanov because without him we wouldn't have such a great platform as Codeforces, where we all can train and develop our passion.
You will again help Limak, your favorite bear. This time it may be harder, because evil Radewoosh will try to disturb him.
We wish you good luck and great fun! Can't wait to see you during the contest! :D
