 The Nordic Collegiate Programming Contest (NCPC) is an annual team-based programming contest aimed at university and college students in the Nordic and Baltic countries. NCPC takes place at at many participating universities and colleges. The same problem set is used at all sites. NCPC results are aggregated electronically, and the event simultaneously serves as local, national, and Nordic championships.

+

+
+We are seeking you problem ideas for NCPC 2025!
+
+You can submit problems in two ways:
+
+1. By e-mailing a problem idea to head of jury Nils Gustafsson <[[email protected]](mailto:[email protected])> no later than Sunday, July 20 2025.
+2. By submitting a problem to NWERC and marking it as a simultaneous submission to NCPC. Further instructions will appear at [https://2025.nwerc.eu/](https://2025.nwerc.eu/) shortly.
+
+If you go for option 1, the following instructions apply. A problem proposal should consist of a draft of a problem statement (simple text file is fine), as well as a short description of the intended solution. Test data and a sample solution is appreciated, but not required. It should be possible to implement the intended solution with at most a few hundred lines of code and it should not take more than a couple of seconds to run. See [https://nordic.icpc.io/archive](/archive.md) for previous years' problems.
+
+Note that if you submit a problem and it's selected you can not participate in NCPC.
+
+Communication regarding the problem selection and later problem preparation is handled through a mailing list, which you will be added to if you propose a problem.
