About

WMOJ is a modern online judge and competitive programming platform. Founded by the White Oaks Computer Science Club, it has grown into a major competitive programming platform open to everyone around the world.

We host problems from past CCC, CCO, COCI, IOI and JOI competitions, as well as various problems from other sources. We also run our own WMOJ Monthly Open Programming Competition (WMOPC) for anyone interested in competitive programming.

This application is completely open source. Feel free to contribute to the project.
