Codeforces Round #105 will take place on February 2nd, 20:00 Moscow time.
This is a themed round, based on the fairy tales I write in Russian.
In this round we decided to conduct an experiment on smoothing the effects of problem setters misestimating the complexities of the problems: all problems have point values of 1000. We tried to order the problems by increasing difficulty, but this is a subjective opinion, so surprises are possible.
Good luck at the round!
