Hi!
After a long break, on Jan 25, 17:35 MSK will be held Educational Codeforces Round 17.
The problemset, in my opinion, turned out to be well balanced and should be interesting for both novices and experienced participants. Task F may end up beneficial for many reds :)
The ideas for problems are by MikeMirzayanov and me. Thanks to fcspartakm for helping in preparation of this round.
I hope you will enjoy the problems and good luck!
