Hello, dear participants of Codeforces community!
Starting from Codeforces Round #327 I'll be the new coordinator and will manage preparation process for all regular Codeforces rounds and other contests held on this platform. I'll do my best to increase the quality of contests we offer you, though Zlobober already raised this bar high. Let's cheer him once again, for all the great job he had done!
Tomorrow round will be held using the problems of Moscow team olympiad for high-school students. Do not be tricked by the word "school" — there will be a gold medalist of IOI 2015 participating and some candidates to this year Russian IOI team, meaning the level of the problems will be appropriate. I am sure everyone will find an interesting problem to enjoy.
The problemset was prepared by the team of Moscow authors (list is incomplete): Zlobober, romanandreev, _meshanya_, wilwell, glebushka98, timgaripov, thefacetakt, haku, Lhic, Timus, Sender, sankear, iskhakovt, andrewgark, masterOK, StopKran, AleX leaded by your humble servant GlebsHP and the chairman of the jury Helen Andreeva.
Five problems will be offered in both divisions and the scoring distribution will be announced later (good traditions should live).
