Codeforces Round #439 (Div. 2)

Revision en17, by Tommyr7, 2017-10-06 19:35:32

Hi, Codeforces!

I'm quite excited to invite you to Codeforces Round #439 (Div. 2) which takes place at 16:35 MSK on 6 October and lasts for two hours.

One of the five problems is created by quailty, and the others are created by me. This is our first round here.

The round couldn't have been realized without efforts of KAN and vintage_Vlad_Makeev. Besides, I also want to say thanks to our testers: cyand1317, visitWorld, Nisiyama_Suzune, cdkrot and 300iq. Thanks for your help to the contest. Also, thanks to MikeMirzayanov with the fantastic Codeforces and Polygon platforms.

The contest will consist of five problems and it is rated for Div. 2 contestants. The same as before, Div. 1 contestants can take part out of competition.

The problems will feature... Well, let's wait and see for another time ;) As per Codeforces tradition, moderate length text and no spoilers about the actual plot.

I hope you can have fun during the contest. Good luck and have fun, wish you high rating!

The scoring distribution will be announced later.

See you tomorrow!

UPD1 : The scoring distribution is 500-1000-1500-2250-2500.
