After a long break, on Jan 25, 17:35 MSK will be held Educational Codeforces Round 17.
You will be given 6 tasks and 2 hours to solve them. 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 :)
I hope you will enjoy the problems and good luck!
UPD: The contest is over. Probably a little bit on the hard side for the beginners? Sorry! Editorial will be in the form of hints and will appear shortly.
UPD3: Challenge phase is over! Congratulations to winners:
Also, top hackers!
If you want to share your ideas about tasks for next Educational Rounds, you can use the new problem proposal form. Please, use prefix "er-" in the name of the task so that we know that it is for Educational Rounds.
