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.
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!
P.S: Top IOI participant in each division (only with handle present in this list) will be rewarded with Persian souvenirs in Kazan.
UPD: Totally unrelated, but since the previous IOI group in telegram no longer exists, here's a new group!
UPD: Scoring is 500 — 1250 — 1250 — 2000 — 2500 in Div.1 and 500 — 1000 — 1500 — 2250 — 2250 in Div.2
UPD: I'm really sorry about the difficulty. System test is about to begin.
