Data Structures & Algo in C++

Learn Data Structures & Algorithms in C++, step by step, with a built-in compiler and AI tutor — for coding interviews, campus placements and computer science fundamentals.

🌟 KEY FEATURES

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

💻 Code in a real C++ runner
Solve problems in a built-in mobile code editor and compiler. Run your C++ solutions against hidden test cases, compare with optimized 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 topic-wise quizzes that climb from Easy to Medium to Hard, with a detailed explanation behind every answer and automatic flags for weak topics. Tackle greedy algorithms and dynamic programming with classics like knapsack, longest increasing subsequence, longest common subsequence and matrix DP. Review attempts anytime in your quiz history.

🤖 Smart Mentor AI tutor
Ask anything about a binary tree traversal or a tricky graph algorithm, get lesson-aware hints, snap a photo of your code or a diagram, and run a realistic mock-interview session. An AI-built 7-day study 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.
