Algo Mind turns abstract algorithms into something you can see. Every lesson pairs a step-by-step animated visualization with synced, highlighted code — you watch pointers move, trees grow, and tables fill in until the idea actually clicks. Stop memorizing solutions; learn the patterns behind them. WATCH ALGORITHMS THINK • 164 classic problems fully animated — play, pause, and step through at your own pace • Code highlighted in sync with the animation, line by line • A live memory view shows variables, pointers, and call frames as they change • Arrays, hash maps, linked lists, stacks, queues, binary trees, tries, heaps, graphs, matrices, DP tables, recursion stacks, sliding windows, and bit operations — one consistent visual language 1,576 PROBLEMS DEEP • The full interview canon, from Two Sum to hard dynamic programming • Solutions in four languages: Python, Java, Kotlin, and C++ • Plain-language explanations, worked examples, and time/space complexity for every problem • Filter by topic, difficulty, company, or your bookmarks — and track every solve A CLEAR PATH • Eight chapters from Foundations to interview-ready, picking up exactly where you left off • 21 animated cheatsheets with nearly 500 animated steps and predict-the-next-step quizzes — perfect for a fast review the night before an interview PRACTICE THAT STICKS • Quick 5, Daily Mix, weak-spot review, or build your own session by topic, difficulty, and company • Three question types: order the steps, true/false concept checks, and 176 fill-in-the-blank code puzzles • Timed Rank Mode for when you want a little pressure STAY ON TRACK • Daily streaks that count any learning activity • XP and per-topic progress tracking • Bookmarks and optional study reminders • Full dark mode • Core lessons work offline • No ads, ever START TODAY A selection of sample problems, puzzles, and cheatsheets is free.
