Hello, Codeforces!
Congratulations to the 22 on the start of the new olympiad season! I wish your olympiad season a good one. I especially wish success to 11th graders, who will have to choose universities and apply for them this year.
I would like to invite you to participate in the mirror phase 1 of the National Olympiad in Informatics. The mirror will be held on codeforces.
This competition will be interesting rather for weaker participants (grey — turquoise on codeforces). The contest should not be difficult for experienced competitors.
The [contest_time:392106] will take place at [contest:392106].
The competition is by IOI standards (partial points, test groups). You will be given 4 tasks for 5 hours
Unrated round
Use of any material published before the round is permitted.
Tasks together with me were proofread for errors and tested by Irsanik, xyz., opPO, ma_sad.
Many thanks to MikeMirzayanov for Polygon and Codeforces.
Thanks a lot to Borunov for help with tournament setup in Yandex Contest system!
