Revision en10, by allllekssssa, 2015-06-13 00:16:23

Hello Codeforces community !

I am glad to announce Codeforces Round 307 (Div. 2) on 12th of June at 19:30 MSK. Authors of this contest are Nikola Mandic (nikola12345) and Aleksa Plavsic (allllekssssa). 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 Zlobober for help in preparing contest and great advices, Delinur for translating problems statements into Russian and MikeMirzayanov for fantastic Codeforces and Polygon platform !

We wish you great fun, a lot of Successful hacks, Accepted solutions and high rating !

UPD: Scoring distribution: 500 — 1250 — 1750 — 2000 — 2500.

UPD2: Due to technical reasons round was delayed by 10 minutes. Stay tuned!

UPD3: +5 minutes. Thanks for your patience!

UPD4: System testing is complete, but the rating update won't be that fast since we are working on improving our cheater catching system. Thanks for your understanding!

Congratulations to winners!
