Hello, Codeforces! I'd like to invite you to Codeforces Round #289 (Div. 2). It'll be held on Saturday, January 31 at 15:00 MSK and as usual Div. 1 participants can take part out of competition.
This round will be carried out according to the ACM rules, which means that you get verdict of your solution on-line, and the duration time is 3 hours.
These differences in the rules are caused by the fact that this round is the second qualifying round for the WCC, which stands for Winter Computer Camp and can be also mentioned as ZKSH. Official school website — hhttp://it-edu.mipt.ru/en/zksh2015. There you can find the selection rules for WCC.
If you are a school student and you want to participate in the selection to WCC here are the steps:
- Sign up for the school at http://goo.gl/kz2qSf, if it was not done earlier.
- Create a free account at codeforces.com, if it was not done earlier.
- Sign up for the round on the link http://codeforces.net/contestRegistration/509. You should put a tick in the box "Do you want to participate in the selection to WCC?", and provide your last name, first name and email, which you entered for registration in the first step.
If you have any questions feel free to write to the address of the organizing committee: [email protected].
The authors of the contest (WCC technical committee) are really grateful to Max Akhmedov (Zlobober) for the help with preparation of this round, Maria Belova (Delinur) for translation of statements and Mike Mirzayanov (MikeMirzayanov) for contribution to the development of programming by creating systems Codeforces and Polygon.
