Practice

For practice, we highly recommend registering for an account at Raffles Institution's online judge platform.

This platform hosts over a thousand practice and past competition problem sets and is accessible by students from any school.

You may access the platform without logging in if you do not need the automatic judging feature. You may find questions from last iteration's problem set here.

Testdata

Testdata and solution descriptions for past competition problem sets are currently maintained at https://github.com/ranaldmiao/sg_noi_archive
