Coding Interview vs Algoritmia

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. An optional Algo Mind Premium subscription unlocks the full library. Subscriptions renew automatically and can be managed in your App Store account settings.

Algoritmia is a visual tool for designing, writing, and running algorithms. Built for students and teachers learning or teaching programming, computational logic, and algorithm design. Create flowcharts by dragging classic shapes onto the canvas, or write the algorithm directly in pseudocode — the app converts between the two representations live. Run the algorithm step by step, watch how variables change, and review the visual output. FEATURES • Flowchart and pseudocode synced in real time. • Complete control structures: conditionals, loops (for/while), multi-way selection (switch/case) and decisions with up to 3 branches. • Visual step-by-step execution with a halo on the active component and the matching editor line highlighted. • Built-in trace table: each step shows variables and outputs in a single row. Exportable to CSV and PDF. • In-app help with reference of all built-in functions and operators (sqrt, round, length, concat, and more). • Pre-loaded examples: factorial, fibonacci, even or odd, max of three, multiplication table, series sum, sum and maximum of an array, 2D table. • 17 UI languages, with pseudocode keywords localized in the 14 languages with established pedagogical tradition. • Folder structure to organize your algorithms. • Import and export individual files (.dpa) or full collections (.zip). • Export the flowchart to PNG, the full document to PDF, or copy the pseudocode to the clipboard. • Light and dark theme follows the system setting. WHO IS IT FOR First-year programming students, teachers of algorithms and computational logic, and self-learners who want to visualize the flow of their ideas before coding them in a real language. PRIVACY Algoritmia works without a user account, without sign-in, and without sending your algorithms to any server. All information stays on your device. We do not collect personal data.
