Complete learning guides — not just topic lists. Each roadmap shows what you'll learn, what you need first, and exactly what you'll achieve, with curated problems and company-tagged practice.
Build unshakeable fundamentals from zero
Start here if you're new to Data Structures & Algorithms. Master the core structures and the problem-solving instincts you'll rely on for everything that follows.
The complete path to a top-tier offer
The high-frequency topics and patterns that dominate interviews at Google, Amazon, Microsoft, Meta and other top companies — end to end, with company-tagged practice.
Turn DP from your weakness into your edge
DP trips up more candidates than any other topic. Work through it systematically — from memoization and tabulation to advanced state design — until it clicks.
Traversals, shortest paths & everything between
The graph toolkit that shows up in system-heavy interviews and contests — from BFS/DFS to Dijkstra, union-find and topological sort.
Go beyond interviews into contest territory
Number theory, bit tricks, geometry and the math that powers competitive contests — for those aiming at Codeforces, ICPC and beyond.
