Hello codeforces community. I'm interested in finding mathematical problem-solving platforms similar to programming contest online judges. Currently I'm aware of projectEuler and onlineMathContest, could anyone recommend other platforms that offer competitive level math problems/contests & have automated submission/judging system? Platforms in any language (English/Japanese/Russian/...) are acceptable.
