Soon is coming Round 1 of the All-Russian Programming Championship CROC-2013. Contestants who gain a score equal to the 400-th place finisher score or greater will advance to the Round 2 (also you need to gain positive score).
Round will be held by usual Codeforces rules (with hacks and decreasing values of the problems). During the round the problems are judged only on pretests and system testing will take place after the end of the contest. The pretests do not cover all possible cases of input data, test your programs carefully.
Before the end of the round it is strictly forbidden to publish the problem statements/solutions/any thoughts and ideas about them elsewhere. It is forbidden to talk about the problems, discuss the statements, solutions and so on.
The problems were prepared by the group of authors: Pavel Kholkin (HolkinPV), Gerald Agapov (Gerald) and Michael Mirzayanov (MikeMirzayanov). I will add that our team have already prepared for you qualification round and answered the questions during the whole competition. Traditionally thanks to Mary Belova (Delinur) for translating the problems.
UPD1: The problems are sorted by increasing of estimated difficulty. The score dustribution is decided to be not standard a little bit : 1000, 1000, 1500, 2000, 2500.
UPD2: due to the large number of participants, it is decided that it will not be able to participate out the competition. For official contest participants the round will be rated.
We wish all the participants good luck and successful advance to the next round of competition.
