About BaseCase

BaseCase is a topic-wise DSA roadmap built on top of real LeetCode and CodeChef data — not a generic list of links, but a curated path where every topic is explained before you're asked to practice it, and your progress across both platforms is tracked in one place.

It exists because most DSA prep is either a wall of unsorted problems or a paid course. This is neither: it's free, and built and maintained by one person actively going through the same prep.
