Codeforces Round #223 will take place on Sunday, January 12th at 19:30 MSK. This is my tenth Codeforces round and I hope not the last.
I strongly recommend you to read ALL the problems.
This is the first round this year. Incidentally, the first round last year for both divisions was also mine (by statistics +1/-1 is was the coolest of rounds that I gave). I hope that this time the problems will be even more interesting for you. Will it? Will find it out after the round :)
Gl & hf ! :)
Problem point values will be standart for both divisions.
