Hello Codeforces community !↵
↵
I am glad to announce Codeforces Round 307 (Div. 2) on [12th of June at 19:30 MSK](http://www.timeanddate.com/worldclock/fixedtime.html?day=12&month=6&year=2015&hour=19&min=30&sec=0&p1=166). Authors of this contest are Nikola Mandic ([user:nikola12345,2015-06-11]) and Aleksa Plavsic ([user:allllekssssa,2015-06-11]). This is our first round and we really tried to make interesting and solvable problems. Traditionally Div.1 participants can take part out of the competition ( personally I believe that the problems are worth to Div 1 participants, and nobody can solve everything in 20 minutes ). This is the first Serbian round and we want to invite our friends from Serbia to take part in this round and maybe prepare some of next rounds.↵

The main character of this round is gonna be GukiZ ( our proffesor of computer science ). He really helps us to become better people and developers ! ↵
↵
We want to thank [user:Zlobober,2015-06-11] for help in preparing contest and great advices, [user:Delinur,2015-06-11] for translating problems statements into Russian and [user:MikeMirzayanov,2015-06-11] for fantastic Codeforces and Polygon platform !↵

Score distribution will be posted later.↵
