DSA Roadmap

DSA Roadmap turns the standard data-structures-and-algorithms interview syllabus into something you can actually watch happen. 28 topics across 12 categories — Arrays, Sorting, Linked Lists, Stacks & Queues, Hashing, Trees, Heaps, Graphs, Dynamic Programming, Backtracking, and more — each with a written explanation, a plain-English analogy, and a step-by-step visualizer you control: play, pause, step forward/back, or scrub to any point like a video. PREDICT MODE Don't just watch — think ahead. Every visualizer can flip into a quiz: playback pauses right before each decision point (a comparison, a branch, a placement) and asks you to guess what happens next before revealing it.
