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. BUILT-IN PROGRESS Track what you've covered with streaks, checkmarks, and category progress bars — all stored right on your device. No account, no sign-up. WHAT'S FREE Big-O Notation, Linear Search, Binary Search, Bubble Sort, Two Pointers, Singly Linked List, Stack, Hash Table, Binary Search Tree, and Selection Sort — ten full topics, no strings attached. Unlock the remaining 18 topics (Merge/Quick/Heap Sort, Sliding Window, Queue, Trie, Union-Find, Binary Heap, BFS/DFS, Dijkstra's, Topological Sort, DP, N-Queens, and more) with a single one-time purchase — no subscription, yours forever. Whether you're prepping for interviews or just want algorithms to finally click, DSA Roadmap is built to make the "aha" moment come faster.
