Hello Codeforces!
You are invited to join ICPC Asia Bangkok Regional Contest 2025 on Nov/08/2025 09:00 (Moscow time). This is an online mirror contest for the ICPC Asia Bangkok Regional Contest 2025, which was held on November 2nd, 2025. The duration of the contest will be 5 hours, and the contest is best for teams of three people. The mirror will use the ICPC format. You can join via the invitation here when the registration window is open.
The contest tasks were proposed by the task authors (jonathanirvings, Mentholzzz, omsincoconut, PineapplesOnPizza, PoonYaPat, sleepntsheep and Snowfall), prepared and polished by the judge team (Lucina, Mentholzzz, nattee, PineapplesOnPizza, PoonYaPat and Snowfall).
We also would like to thank MikeMirzayanov for Codeforces and Polygon. The contest would be impossible without Polygon!
We hope you enjoy the contest.
update. The registration is now open.
update 2 The mirror is now finished, and the contest is now publicly available. Thank you for your participation — both onsite and mirror. Also, congratulations to the winner: Just use CRT. The short, rough sketch of the editorial is now in the contest material.
Thank you for your kindness and sharing. We are very eager to up-solve the interesting problems from the contest. At November 7, 11am GMT+7, the link to contest is still not published yet. Can I ask if it's all well prepared?
You can join via the invitation link in the blog. Unfortunately, I cannot increase the registration window in the gym, so you must wait until 6 hours before the contest to register.
Hey! We're really excited to take part in the contest, but we wanted to ask if it could be preponed since we have the ICPC India online round scheduled right after it. It would be great if we could attempt this contest as practice. Is that possible? Thanks in advance!!
