Codeforces Round 974 (Div. 3)
Difference between en11 and en12, changed 77 character(s)
Hello Codeforces! ↵

Greetings from Nottingham, England! We are delighted to invite you to _Legend of Robin Hood_, a round inspired by our local folklore.↵

[contest:2014] will start on [contest_time:2014].↵
 ↵
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**. After open hacks all accepted solutions will be rejudged on successful hacks.↵

You will be given **6-8 problems** and **2 hours and 15 minutes** to solve them.↵

Note that the **penalty** for the wrong submission in this round is **10 minutes**.↵

[Remember](https://mirror.codeforces.com/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.**↵

Problems have been prepared by↵
