Hello, Codeforces community!
We are happy to invite you to participate in National University of Singapore (NUS) CS3233 Final Team Contest 2026 Mirror on Apr/13/2026 12:15 (Moscow time). CS3233 is a course offered by NUS to prepare students in competitive problem solving.
The contest is unofficial and will be held in Codeforces Gym. Standard ICPC rules (Unrated, ICPC Rules, Teams Preferred) apply. The contest is unrated. Note the unusual starting time.
The problems are written and prepared by kai824, feeder1, hoangnguyen09022004, hihihaha, ruanxiaoyu, evolto, BJoozz.
We would also like to thank:
- Prof. Steven Halim for coordinating and teaching the CS3233 course;
- hoangnguyen09022004 as my fellow teaching assistant;
- errorgorn for existing;
- the Kattis team for the platform used in the CS3233 course and in the official contest; and finally
- MikeMirzayanov for the amazing Codeforces and Polygon platform!
The contest will last for 5 hours and consist of 13 problems. While it is preferred to participate in a team, individual participation is also allowed.
The problems themselves may be quite standard as they are targeted toward those who have just learned competitive problem solving. However, we have also included a few challenging problems for stronger teams, such as ex-IOI or ICPC participants taking part in the course as well. So, the participants can expect a good mix of problems of varying difficulty levels, that we hope can be educational!
We hope you will enjoy and have fun in the contest. Good luck!
UPD: Thank you for your participation, sorry for the issues with the long queue. Editorial has been uploaded here
