Hello Codeforces!
I am pleased to invite you all to participate in Codeforces Round 981 (Div. 3), which will start on Oct/24/2024 17:35 (Moscow time).
The format of the event will be like any Div. 3 rounds:
6-8 tasks;
ICPC rules with a penalty of 10 minutes for an incorrect submission;
12-hour phase of open hacks after the end of the round (hacks do not give additional points)
after the end of the open hacking phase, all solutions will be tested on the updated set of tests, and the ratings recalculated
by default, only "trusted" participants are shown in the results table.
I encourage participants with a rating of 1600+ not to create new accounts but to participate unofficially.
Only trusted participants of the third division will be included in the official standings table. This is a forced 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 (or you are a newcomer/unrated), then the round will be rated for you.
Also, it will be a round with unrated register. If you already registered as rated participant you can change registration type here.
I would like to thank
