DSA preparation in C++

Master DSA — data structures and algorithms in C++ — step by step with a built-in mobile code compiler, native code editor, and an interactive AI learning tutor. This C++ placement preparation app supports software engineering students and professionals preparing for technical coding interviews, campus placement drives, and general problem-solving studies.

📚 DATA STRUCTURES FOUNDATION
Study detailed programming lessons covering arrays, strings, linked lists, stacks, queues, and hashing, then progress into binary trees, graphs, heaps, and tries. Every sub-topic features thorough algorithmic theory, guided coding practice, and explicit time and space complexity analysis using Big O notation, and a quick check quiz confirms each lesson.

⚙️ ALGORITHM PATTERNS THAT WIN INTERVIEWS
Master sorting, searching, recursion, two-pointer, and sliding-window patterns, then tackle greedy algorithms and dynamic programming (DP) through classic problems like the knapsack problem, longest common subsequence, and matrix DP.

💻 MOBILE CODE RUNNER & COMPILER
Solve coding problems directly in the native code editor and compiler — no setup. Execute your C++ solutions against hidden unit test cases, compare with optimized reference answers, and watch algorithms execute live. The runner also supports Java, Python, JavaScript, Go, Rust, and Kotlin.

🎯 ALGO LAB: FAANG-STYLE PROBLEMS
Open the dedicated Algo Lab to solve high-yield FAANG and MAMAA algorithmic coding problems with comprehensive, optimized solutions — the questions top tech companies actually ask.

📝 QUIZZES, MOCK TESTS & INTERVIEW QUESTIONS
Take topic-wise quizzes that scale from easy to hard, with detailed logical explanations behind every answer and automatic flagging of your low-accuracy weak areas. Timed mock tests blend theory, MCQs, and coding with result analytics, and curated interview questions come with hints and model answers.

🔁 SPACED REPETITION
Every question you get wrong is queued for spaced-repetition review, returning at smart intervals until you truly know it — weak topics get fixed before the interview.

🤖 INTERACTIVE SMART MENTOR AI TUTOR
Never stay stuck on a difficult binary tree traversal or a confusing graph algorithm. Chat for lesson-aware hints, review runtime errors, upload photos of code or diagrams, or run realistic mock interview sessions. An automated seven-day study plan blends concept review with rigorous interview drills.

📊 ANALYTICS, STREAKS & LEADERBOARDS
Monitor your consistency with visual activity charts, tracked study minutes, and completed milestones. Keep a daily check-in streak, earn XP and coding badges, and climb the global engineering leaderboard.

🌐 BUILT FOR EVERYONE
Works offline with light and dark themes, in English, Hindi, Kannada, Tamil, and Telugu with technical term protection to keep code syntax safe.
