Coding Interview vs C++ Starter

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.

C++ Starter is a programming and learning environment for beginners. Learn by writing and running real C++ code, progressing from basic syntax to algorithms, games, graphical interfaces, and network projects. Write, compile, and run C++17 programs directly on iPhone, iPad, and Mac. Provide input and inspect output without setting up a compiler toolchain yourself. Learn by writing code Start with 20 free C++ lessons covering variables, input and output, conditions, loops, functions, strings, containers, structs, and classes. Continue with seven advanced courses through Learning Pro: - C++ Data Processing and the Standard Library - Algorithms and Problem Solving - C++ Object-Oriented Programming and Project Organization - Console Tool Projects - Introduction to Game Programming - Introduction to GUI Programming - Introduction to HTTP Programming Courses are available in English, Simplified Chinese, and Japanese, with explanations, examples, exercises, and reference implementations. Console exercises are checked locally using test inputs and outputs. Game and GUI exercises include interactive checklists. Explore beyond the code Discover the history and applications of C++, learn coding conventions, explore popular libraries, and find recommended books to guide your next steps. App news and contextual tips introduce new features and offer practical guidance for programming and learning. From console programs to interactive projects - Build data-processing tools and algorithms with the standard library - Learn game and graphics programming with raylib - Explore widgets, layouts, and events with TGUI - Learn HTTP requests and server endpoints with CPR and Crow - Edit and run client and server code within the same project A workspace for every screen - C++17 and multiple source files - On-device compilation and execution - Preset input and interactive input - Program output and compiler diagnostics - Automatic code saving - Tab navigation on iPhone, with a landscape layout that leaves more room for your work - Project-focused sidebars on iPad and Mac, with quick access to courses and Explore - Light and Dark Mode support - Multiple projects and advanced library, display, and server settings with IDE Pro Local programming, networking when needed No account registration is required. Project code stays on the current device, and compilation and execution take place locally without uploading your source code to the developer’s servers. Network programs can access external services; data included in requests is sent to the servers specified by your code. Free features and optional purchases The complete C++ Basics course and one editable local workspace for standard C++ are free. IDE Pro is an optional one-time purchase that unlocks multiple projects and advanced project settings. Learning Pro provides access to paid courses for 1, 3, or 12 months, with no automatic renewal. During the access period, you can study all paid courses available in your region. The editing and execution features needed for course exercises are included; no separate IDE Pro purchase is required. From your first program to games, interface tools, and HTTP endpoints, start building with C++ Starter.
