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
