Hi!↵
↵
After a long break, on [Jan 25, 17:35 MSK](https://www.timeanddate.com/worldclock/fixedtime.html?msg=Educational+Codeforces+Round+17&iso=20170125T1735&p1=166) 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 :)↵
↵
The ideas for problems are by [user:MikeMirzayanov,2017-01-24] and me. Thanks to [user:fcspartakm,2017-01-24] for helping in preparation of this round.↵
↵
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.↵
↵
**UPD2:** [Editorial](http://codeforces.com/blog/entry/50010)↵
↵
**UPD3:** Challenge phase is over! Congratulations to winners:↵
