Annyeonghaseyo, Codeforces!
We invite you to participate in Squarepoint Challenge (Codeforces Round 1055, Div. 1 + Div. 2), which will be held on Oct/03/2025 17:35 (Moscow time).
The round will be rated for everyone. You will be given 8 problems, one of which is divided into two subtasks, and 3 hours to solve them. One of the problems will be interactive, so make sure to read the guide for interactive problems before the contest.
The problems are authored and prepared by middle_man, djm03178, ko_osaga, and qwerasdfzxcl.

As some of you may know, this contest originates from my promise to hold a Codeforces round if T1 wins a World Championship, which they did win afterwards in 2023 and 2024. This contest is dedicated to the T1 League of Legends team, and each problem will feature the members of their roster following the 2023 season. They are the sole reason for this project, so I want to extend my thanks to them and wish them the best of luck in their 2025 run! For those who are unfamiliar with the game, don't worry, as the problem statements are written neutrally anyway.
Score distribution is $$$500 + 1500 + 1500 + 2500 + 3000 + 4000 + 4000 + (4000 + 2500)$$$.
