Hello, Codeforces!

We continue the series of contests dedicated to IOI 2016 with IOI 2016 Training Round #4. We will again use problems from past Romanian competitions. For this reason, the round will be unrated.

The contest will take place on Saturday, July/09/2016 11:00 (UTC). This round's difficulty will be similar to the previous ones. Don't forget to register in order to participate.

Contest format:

• You will have to solve 3 tasks in 3 hours.
• There will be full feedback throughout the entire contest.
• The tasks will have partial scoring. The maximum score for each problem will be 100 points.
• There will be no tie breaker, so two users having the same total score at the end of the contest will share the same place in the standings.

The problem authors for this round are Adrian Airinei, Cosmin Gheorghe and Mihai Pătrașcu.

We still recommend using an updated version of Google Chrome. If you find any bugs please email us at contact@csacademy.com

EDIT: The editorial has been posted. Congratulations to the winners!
