End-to-end DSA roadmap · dependency-ordered
Your interview prep, topologically sorted.
Fifteen topics wired as a dependency graph — exactly the way the subject actually works. A node unlocks only when everything it requires is resolved. Click any node to push its stack frame: the patterns to learn, the exact LeetCode set, and the resources that teach them. Finish a topic, mark it resolved, and the graph opens the next frame.
// one valid execution order (Kahn's algorithm, computed live)
next uplocked — resolve deps firstresolvedclick node = push frame · follow a dep chip = push another frame · esc = pop all
The strategy behind this roadmap — the BFS preparation method, the 30-minute rule, and the full resource stack.read →
