CodeArena is a competitive programming tournament featuring multiple rounds. Contestants participate individually, and the tournament consists of two tracks: one exclusively for first-year students and the other for all other students. The tournament begins with a single problem in the first round, from which top contestants proceed to subsequent rounds. Following rounds are 1 vs 1 matchups. In each round, contestants are presented with a single question, and the first to solve it advances to the next round. There is no penalty for wrong answers. After each round, half of the contestants are eliminated until only one winner remains in each track.
