Hello Codeforces
This is Orangutini Ananasini Emoji
SpyrosAliv and I are excited to welcome you to participate in Codeforces Round 1017 (Div. 4) at Apr/13/2025 18:35 (Moscow time). Note the unusual time of the round. You will be given $$$2$$$ hours and $$$15$$$ minutes to solve $$$8$$$ problems.
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.
Note that the penalty for each wrong submission in this round is 10 minutes. Also, note the rule restricting AI use!!! If you are caught using AI, your submissions will be skipped, then your account will be banned, and I will possibly even publicly shame you.
Remember that only the trusted participants of the fourth 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 fourth 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 rating of 1400 or higher.
Regardless of whether you are a trusted participant of the fourth division or not, if your rating is less than 1400, then the round will be rated for you (unless you register unrated).
We would like to thank the following people for making the contest possible:
Vladosiya for coordinating and Russian translations.

EDIT: There used to be a meme picture on this announcement. Unfortunately I was not aware of its potential political implications. It has since been removed.
EDIT 2: As a replacement to the controversial image, we have brought Orangutini Ananasini Emoji. Say hi to Orangutini Ananasini Emoji. Hi Orangutini Ananasini Emoji!
