A synthetic reasoning-trace dataset built from 9,413 Codeforces problems (800–3500 rating). Each problem includes structured wrong-path explorations, discovery narratives, and pseudocode designed to teach models how to think through competitive programming problems, not just solve them.
Most competitive programming datasets pair a problem with a solution. This dataset captures the full reasoning process:
