Codeforces round #238 will start today at 19:30 in Moscow time. The round will be held in both divisions.
The round was prepared by me and cfk. This is the 4th round for me and the 2nd for Krisjanis. I think the problems this time are rather unusual and maybe even surprising. We have no doubt that everyone will find a problem that suits their taste! But you have to find it. (:
As always, thanks to Mikhail Mirzayanov (MikeMirzayanov) for Codeforces and Polygon systems, and Maria Belova (Delinur) for translating the statements. Big thanks to Gerald Agapov (Gerald) for helping in preparation of the contest. Me and Gerald had a chance to talk about the problems onsite during the Petrozavodsk winter camp, which I think was very productive.
We wish you a very exciting round!
UPD1: Score distribution:
DivI: 500 1000 2000 2000 2500
DivII: 500 1000 1500 2000 3000
The scoring for the problems is relative, so that the cost of each problem would be a multiple of 500 and closer to the objective estimate. Don't be afraid, the problems are not really that hard. (:
UPD2: Congratulations to the winners!
UPD4: The contest tutorial is published here.
