CP Tracker

Road to Guardian & Red

A log of every problem attempted, how it was solved, and how long it took — nothing is added until it's actually been attempted. Recommendations draw from NeetCode 250 and the full Codeforces problemset, with the topic taxonomy on youkn0wwho's Topic List as a reference for deeper CP topics.
