Hello! On Saturday 15th September 16:00 UTC the contest HackerEarth HourStorm #3 will take place. It’s the third version of a short contest, that runs for 1 hour! The problem set consists of 3 traditional algorithmic tasks of various difficulties.
For traditional algorithmic tasks, you will receive points for every test case your solution passes — so you can get some points with partial solutions as well. Keeping the IOI tradition alive, the order of the difficulty of getting full points might be different from the order of difficulty of getting partial points, so make sure you read all the tasks. Check contest page for more details about in-contest schedule and rules.
I am the author of the tasks; but don't despair, they'll be (slightly) easier than my last CF round! Many thanks to jtnydv25 for testing and valuable feedback. As usual, there will be some prizes for the top three competitors:
In addition, top 5 on the scoreboard with rating less than 1600 will win HackerEarth t-shirts.
Good luck to everyone, and let's discuss the problems after the contest!

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!
