Hi everyone!

It's the round you've been waiting for... Codeforces Round #420 (Div 2). It will take place tomorrow, 25 June 2017, at 17:35 MSK. As always, Div. 1 participants are encouraged to join out of competition. The round will be rated for Div. 2 participants and will have 5 problems to be completed in 2 hours.

I wouldn't be able to create this round without the help of many people: KAN for lots of help in preparing the contest, 300iq and Alladdin for testing and providing feedback, and as always MikeMirzayanov for the Codeforces and Polygon platforms.

This will be my second contest, and I'm glad to get such a nice round number :). Hopefully, you'll find the problems interesting. Of course, you should read all the problems so you can solve problems you find easy or interesting.

To excite some and disappoint others, the round theme will have nothing to do with the number 420. Instead, continuing the anime themes of the last two rounds, round #420 will feature mad scientist Rintaro Okabe (don't read spoilers!) from the anime Steins;Gate. Statements will not contain any spoilers, but you might find the problems slightly more amusing if you've watched the series. Of course, you should watch the series if you havent :)!

As per Codeforces tradition, scoring distribution will be announced shortly before the contest. Good luck, and I hope you can help Okabe with all 5 tasks :D!
