Hello, Codeforces!↵
↵
On [contest_time:1941] [contest:1941] will start.↵
↵
You will be offered **7 problems**, dedicated to the adventures of a restless mathematician, a programmer and just a funny character named **Rudolf** and his brother Bernard, and **2 hours 15 minutes** to solve them. Problems have 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.↵
↵
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. 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.**↵
