Hello! [contest:1729] will start at [contest_time:1729]. You will be offered 6-8 problems with expected difficulties to compose an interesting competition for participants with ratings up to 1600. However, all of you who wish to take part and have a rating of 1600 or higher, can register for the round unofficially.↵
↵
The round will be hosted by rules of educational rounds (extended ICPC). Thus, solutions will be judged on preliminary tests during the round, and after the round, it will be a 12-hour phase of **open hacks**.↵
↵
You will be given **6-8 problems** and **2 hours and 15 minutes** to solve them. One of the problems in this round is **interactive**. Don't forget to read the [guide on interactive problems](https://codeforces.net/blog/entry/45307).↵
↵
Note that the **penalty** for the wrong submission in this round is **10 minutes**.↵
↵
[Remember](https://codeforces.net/blog/entry/59228) that only the trusted participants of the third division will be included in the official standings table. As it is written by link, this is a compulsory measure for combating unsporting behavior. To qualify as a _trusted participant of the third division_, you must:↵
↵
- take part in at least five rated rounds (and solve at least one problem in each of them)↵
- do not have a point of 1900 or higher in the rating.↵
↵
**Regardless of whether you are a trusted participant of the third division or not, if your rating is less than 1600, then the round will be rated for you.**↵

Thanks to MikeMirzayanov for the platform, help with ideas for problems and for coordination of our work. Problems have been created and written by ITMO University team: ↵
