Hello Codeforces
SpyrosAliv and I are excited to welcome you to participate in Codeforces Round 1047 (Div. 3) at Sep/07/2025 17:35 (Moscow time). You will be given $$$2$$$ hours and $$$15$$$ minutes to solve $$$7$$$ 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.
The penalty for each wrong submission in this round is 10 minutes.
Remember 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 rating of 1900 or higher.
Regardless of whether you are a trusted participant of the fourth division or not, if your rating is less than 1600, 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.
- sammyuri, nifeshe, Intellegent, and temporary1 for carrying me in Bedwars.
- The testers: Dominater069, __baozii__, nifeshe, satyam343, Intellegent, catgirl, Friedrich, cry, temporary1, -firefly-, efishel, 18o3, Arpa, AksLolCoding, Edeeva, reirugan, macaquedev, chromate00, pianapolataa, RobinFromTheHood, yse, Filikec, Non-origination.

Additionally, if you are a tester of EPIC Institute of Technology Round Summer 2025 (Codeforces Round 1036, Div. 1 + Div. 2) and you are rated for Division 3, I will ask you to not participate in the round, as it is possible you have seen some tasks before.
I wish you the best of luck and I hope you enjoy the contest!
