Data Structures & Algo in C++

Learn Data Structures & Algorithms in C++, step by step, with a built-in compiler and AI tutor.

📚 Learn DSA step by step
Clear lessons on arrays, strings, linked lists, stacks, queues and hashing, then trees, graphs, heaps and tries. Each subtopic gives theory, guided practice and a quick summary, with plain-English explanations and time/space complexity you can actually reason about.

💻 Code in a real C++ runner
Solve problems in a built-in editor and compiler. Run your C++ solutions against hidden test cases, compare with reference answers, and watch sorting, searching, recursion, two-pointer and sliding-window patterns come alive. The runner also supports Java, Python, Go, Rust, Kotlin and more.

🧠 Practice that builds intuition
Take quizzes that climb from Easy to Medium to Hard, with an explanation behind every answer and flags for weak topics. Tackle greedy and dynamic programming with classics like knapsack, LIS and matrix DP. Review attempts anytime in your quiz history.

🤖 Smart Mentor AI tutor
Ask anything about a tree traversal or a tricky graph problem, get lesson-aware hints, snap a photo of your code or a diagram, and run a mock-interview session. An AI-built 7-day plan blends concept review, coding practice and interview drills.

📊 Track real progress
See scores over time, study minutes and topics completed. Build streaks with a daily check-in quiz and an AI revision card, and climb global and per-subject leaderboards.

🌐 Built for everyone
Works offline, with light and dark themes and an interface in English, Hindi, Kannada, Tamil and Telugu that keeps code and technical terms intact.

Plans
Starter topics, daily practice and limited AI are included. A subscription unlocks every topic and difficulty, unlimited problem solving, full history and higher AI limits. Available as a 6-month prepaid plan or an auto-renewing monthly plan, each with a trial period.

This app supports interview preparation, campus placement practice, and general problem-solving study.
