Codeforces Beta Round #22 (Div. 2)
By RAD, 14 years ago, translation, In English

Welcome all to Codeforces Beta Round #22

Note that at this time registration is possible during the round. The contest will begin at 19:00 MSK.

Today I am an author of the problems. I would like to thank Mike Mirzayanov for help in contest preparations, Edvard Davtyan and Nickolay Kuznetsov for writing the verification solutions, and Julia Satushina for translating statements into English.

Good luck on the contest!

UPD: The contest is over. Thank you all for participating!

As far I can deduce, the first paragraph says that the event starts at 19:00 and people can register during the contest. The second paragraph mentions the people that helped preparing the contest. The last line should say something like "good luck".

I am green and my rating is 1439. I had registered for round 22, but in the rank list my name appears in the *out of competition* list. Can you kindly look into this issue.
Thanks in advance,
Suhash

      I think this is because you were blue when you registered for the round. I saw that it was possible to register before the Round 19 started.

Yet another sad story...
About 10 minutes left to the end i looked at problem E and knew it is to count the number of SCC and then just pair their roots and finished coding some seconds before end. I still have a bug somewhere but it always happens to me...

I just noticed you can see "Friend Rankings". How do you choose your friends? I can't see anything on my profile page or their profile pages, or on the Friend Rankings screen...

Thanks in advance!

    You can add a friend by clicking a star which is placed to the right of the handle on user's profile page.

      Awesome, thanks!

      That's quite a subtly placed icon.

        Well, probably Google Translate is somewhat bad at Chinesse-Russian translation, but you comment was translated as "I cheated"
