About DSA Playbook

DSA Playbook is a focused interview-prep site. Each topic is a short, visual walkthrough of a classic pattern — binary search variants, sorting internals, tree traversals, DP templates, and core array/string questions.

The idea is simple: reading a solution is not the same as watching indices move. The debugger view shows left / mid / right (or equivalent state) on every step, with a note you can say out loud in an interview.

Content is curated for roughly 1–5 years of experience. Algorithms stay standard; the emphasis is on clarity, vocabulary, and muscle memory.

How it is built

Next.js App Router, Tailwind, and static data modules under /data. A data-loader prefers an API when available and falls back to those modules so the site keeps working offline or before a backend exists.

See the entity schema for the content model and contribution notes.
