Difference between en14 and en15, changed 73 character(s)
Hi all!↵

In two days, at 19:35 MSK Codeforces Round #339 (Div. 1 & Div. 2) will take place. This is an unusual round since we — the problemsetters — are highschool students who participate in the programming training group at high school #179. This round is our first effort and we did our best to make it interesting and bug-free. I invite you all to compete in this round since the problems will be **solvable**, but even [user:tourist,2016-01-13] will have to think over some of them. :)↵

With supervision and control from Mikhail Tikhomirov ([user:endagorion,2016-01-13]), the problems were developed by: Egor Chunaev ([user:ch_egor,2016-01-13]), Vasily Alferov ([user:platypus179,2016-01-13]), Dmitry Sayutin ([user:cdkrot,2016-01-13]), Timofey Gutor ([user:Tigutor,2016-01-13]), Maria Fedorkina ([user:MF2000,2016-01-13]). Mikhail Sorokin ([user:themikemikovi4,2016-01-13]) and Sergey Aleikin ([user:Derrior,2016-01-13]) contributed their problem ideas.↵

We thank Gleb Evstropov ([user:GlebsHP,2016-01-13]) for his help in preparing the contest, Maria Belova ([user:Delinur,2016-01-13]) for translating the statements in English, [user:AlexFetisov,2016-01-14] and [user:winger,2016-01-14] for testing, and, of course, [user:MikeMirzayanov,2016-01-13] for unique CodeForces and Polygon systems.↵

Round will have [standard Codeforces rules](http://codeforces.net/help), with pretests at first, and final tests afterwards. Take care to account for all possible cases.↵

Best of luck to everyone!↵
