Hello ladies and gentlemen.
I'm honored to announce you that Codeforces Round #366(or should I say, IOI 2016 opening CF contest) is gonna take place on August 7th and I'm the writer. Please note that the timing is unusual.
As usual, there are 5 problems in each division and duration is 2 hours.
I want to thank LiTi for testing this round, GlebsHP for helping me prepare it and MikeMirzayanov for legendary and unique platforms of Polygon and CF.
The main characters of this round are The Avengers!
I wish you all Accepted solutions and Successful hacks.
Scoring will be posted soon.
Problems are sorted by their expected difficulty, but I strictly recommend you to read all the problems.
GL & HF!
