After so much time, I finally reached 1900 (at last). Although I now have 1900, I didn't experience any real sense of inner satisfaction—after all, I didn't make it to the final stage of the All-Russian Olympiad. By the way, here's a strange tip for those competing on Codeforces: don't try to come up with something complex on ABC problems—more often than not, the problem is easier than you think. Good luck to everyone and bon appétit!
