Hello, Codeforces! I'm pleased to announce the 5th stage of the 2nd Universal Cup. It will be held from October 14th to October 15th.↵
↵
The contest was prepared for you by the SPbSU LOUD Enough team ([user:tranquility,2023-10-11], [user:nikgaevoy,2023-10-11] and [user:Kaban-5,2023-10-11]), a bronze medalist of ICPC World Finals in Dhaka. We (the authors) would also like to thank [user:Gassa,2023-10-11], [user:snarknews,2023-10-11] and [user:SoshkinRoman,2023-10-11] for some useful feedback and technical assistance. And, of course, we would like to thank the organizers of Universal Cup for letting us hold our contest as a stage of Universal Cup and share it with a wider audience.↵

This contest was first used in the Petrozavodsk Programming Camp Winter 2023, and also appeared in the 2023 ICPC Training Camp powered by Huawei and the Hello Muscat 2023 Bootcamp. **If you participated in any of those, please refrain from participating in this stage of the Universal Cup**.↵
↵
It is important to note that this stage is much more difficult than an average ICPC regional. **Solving even a couple of problems is already an achievement**.↵
↵
We think that all problems contain interesting ideas in them and we are delighted to share them with the community. ↵
In particular, we think that teams preparing for ICPC World Finals have a lot to learn from our contest.↵
Good luck and have fun!↵
↵
Let's meet in the comments to discuss the problems after the last time window for the contest finishes! We will update the post with a link to the editorial shortly after that. You are encouraged to share different approaches and talk about the problemset in general.↵
↵
**Update.** As promised, you can find the editorial here: https://acm.math.spbu.ru/trains/231014_northern/ <br>↵
It is a bit sketchy, so feel free to ask additional questions about the problems and their solutions.↵
