A working log of DSA problems I've solved across CodeForces, CodeChef, HackerRank and Coding Ninjas — committed as I learn, mistakes included.
This is where I keep the code from every problem I sit down and actually solve — not a curated portfolio, just the raw history. Some files are one-liners from a first CodeChef attempt, some are Codeforces Div-2 A's, some are half-finished course scaffolds.
I'm a B.Tech IT student building toward a full-stack + DSA foundation. This repo is the DSA half of that — the MERN half lives in a separate practice log.
