Hello 2019

Revision en9, by Radewoosh, 2019-01-05 02:44:34

Hello coders! I hope that you are enjoying the New Year as much as me. To make its beginning even greater, Codeforces is going to host a contest and I will be an author of all tasks. Hello 2019 will take place on Friday.

Using the opportunity, I want to thank to:

  • Lewin and mnbvmar for testing the round.
  • mnbvmar for indescribably helpful discussions about problems.
  • cdkrot and KAN for round coordination and help with preparation.
  • MikeMirzayanov for such great platforms (you know which ones :P).

The round will consist of 8 problems and you will be given two and a half three hours to solve them. Yes, the round will be rated.

There will be no interactive problems, but if you want you can read this document anyway, it's always good to learn new things.

Good luck and see you during the contest!

UPD1: Editorial

UPD2: I'll be on the Discord channel after the contest, so you will be able to ask me about the problems.

UPD3: You're probably wondering what the statements will be about. I hope that it will be another great year for Codeforces. As it's the community that creates it, I decided to write statements about the people who already have or had their part in Codeforces' history. As I wanted to be objective, the statements will be about 8 people who triumphed the most times in CF rounds. Using the opportunity, I want to invite these 8 people to take part in the contest. Let's say that the first person who will guess the set in the comments wins some free contribution. Good luck!

UPD4: The round will be 3 hours long.

UPD5: The drain will be adjusted and the scoring will be 500-1000-1500-2000-2750-3000-3500-4000.

UPD6: The round is over, congratulations to the winners!

  5. Petr

And to the first-to-solvers!

UPD7: Editorial
