[CSSA x OUCC] Programming Contest / 競プロコンテスト

Starts in


We have partnered with the ANU Computer Science Students' Association (CSSA) and Osaka University Computer Club (OUCC) to bring you our first INTERNATIONAL competitive programming competition!

What is competitive programming?

The competition consists of a series of algorithmic problems that you can solve with simple programs in a programming language of your choice. Challenges range in difficulty from very approachable to challenging, so there's something for everyone.

You do not need any algorithms / data structures background knowledge (but don't be fooled by this! Some of the questions are still difficult!)

This is a friendly competition with our new international friends, so it'd be great to get as many participants as are interested.

  • Ranking is by score. Tie breaks are decided by the time of the last submission that got the points.
