Just a reminder that the registration for this year's deadline24 is going to close in about 4 days. If you are going to participate you should register in the next few days.
The qualification round will be held next Sunday (February 25, 2018, 9:00-14:00 (CET)). Let's discuss the problems here after it.
UPDATE: The registration will end in about a day and 4 hours.
There is a blog about it on the main page: http://codeforces.com/blog/entry/57768
