For context, "preOJIA" and "preONIA" contests are preparatory rounds for Romania's regional and national phases, respectively. AICC stands for "AI Community Contest", a practice monthly contest for international AI olympiads.

Rated difficulties are relative to IOAI, where easy tasks can be solved with classic approaches, and medium/hard tasks require deeper thinking or sometimes using ideas from newer research papers.
