Hello Codeforces!

We are here to invite you to Codeforces Round #614 (Div. 1) and Codeforces Round #614 (Div. 2), which will take place at Jan/19/2020 16:35 (Moscow time). The round is rated for both divisions.

This is our first round including Div.1 parts, hopefully you'll find the problems interesting. ;)

This round is themed based on the Rayark Inc.'s rhythm game, "Cytus II". You are about to help our characters in various problems, whether inside or outside of the virtual Internet! Also, feel free to listen to the music tracks I've chosen from the game for each problem (and later, editorial!). ;)

Each division will be given 6 problems to solve in 2 hours. The round's problems were prepared by Xuan-Quang xuanquang1999 D. Nguyen, Duy-Bach Akikaze Le and Tuan-Dung low_ To.

Interactive problem(s) might be found in this round. Learn about them here.

We also want to thanks our friends for helping this contest being possible:

Last but not least, I want to give a huge appreciation to MikeMirzayanov for the awesome Codeforces and Polygon platform, which makes this contest possible.

Wish everyone good luck and high rating!

UPD1: Editorial is available here.

UPD2: Many more testers helped us in this round! Huge thanks to Kevin ksun48 Sun, Andrew ecnerwala He, Aydar aid Sayranov, Nikolay KAN Kalinin, Oleg Mustang98 Vallas, Mohammed mohammedehab2002 Ehab, Artem Rox Plotkin, Mingming Nero Zhang, Darko Aleksic, Ilya IlyaCK Porublyov, NatInTheHat and NIWIS!

    Then next comes Cytus I, Deemo, VOEZ, Dynamix, Lanota, Hachi Hachi, Tone Sphere, Zyon

    I wonder if anyone has the guts to make a round themed on Bandori, iDOLM@STER, or LLSIF. That'll be hilarious to see XD

    I'm not sure if I could create a SDVX themed contest anytime soon...
    Anyway, the song is quite popular in many rhythm games so I guess it ain't a poor choice.

Anime in the announcement is a troubling sign. Please, do not put irrelevant pictures into the statements, or at very least ensure that they are not too big or heavy.

Really surprised when seeing the poster of 'Cytus II' on the main page of Codeforces.

I believe it will be an amazing contest!

Anyway, I'm curious about whether Deemo will participate in this contest. XD
