The round 1 of VK Cup 2018 will take place on March 10 at 18:35 MSK (check your timezone). The contest "VK Cup 2018 — Round 1" is for teams qualified from two Qualification Rounds. The top 400 teams will advance to the Round 2, along with teams that qualify in the Wild Card Round 1 a week later. As usual, there will be two parallel rounds for those ineligible to participate in VK Cup, one for each division.

I'd like to thank KAN for steering my crazy ideas into a coherent unit, the coordination and also for suggesting one of the problems, AlexFetisov, qwerty787788, winger, Errichto, Tommyr7 and misof for testing the problems, MikeMirzayanov for building Codeforces and Polygon and VK for organising the contest.

All three rounds last 2 hours, and all are rated. The VK Cup and Div. 1 will have six identical problems while the Div. 2 contest will consist of five problems. The scoring distribution will be announced before the contest.

The main heroes of this round will be Alice and Bob. Beware that Eve might attempt to foil their plans.

This is my first round on Codeforces and hopefully not the last. Wish you many submissions, high hacks and successful rating.

UPDATE: The scoring in Div.1 and VK Cup round 1 is 500-1000-1500-1750-2250-3000. For Div.2, it is 500-1000-1500-2000-2250.

UPDATE2: The round is finished. I hope you enjoyed it. Tune in a bit later for editorial.

UPDATE3: Congratulations to winners!
