Greetings good people of Codeforces. I hope you're having a great week.
The contest will be held on Friday, December 20, 2019 at 15:00 UTC+06.
You will be given 12 problems in total and 5 hours to solve them. The contest will follow standard ICPC rules.
We tried to create very engaging problems, compact statements and robust datasets for this round. We hope that EVERYONE will find the problems stimulating and interesting. You can also participate as a team.
Note to anyone who participated in the onsite contest, please refrain from sharing or discussing the problems here before the contest.
Also, there will be an interactive problem. If you don't know about interactive problems, please refer to this article.
Good Luck! See you on the leaderboard!
UPD: BUMP! 1 hour to go, buckle up!
