Data Structures and Algorithms
Professional DSA Learning App
Free · In-App Purchases
DSA is a visual learning app for computer science students, exam prep, and self-learners. Turn abstract data structure concepts into step-by-step animations so you can actually see how algorithms work.
WHY DSA
• Dual-mode learning: read concept lessons first, then run interactive step-by-step visualizers
• Smooth animations: pointer moves, swaps, assignments, and tree restructuring are animated with clear step descriptions
• Structured curriculum: organized by textbook chapters from fundamentals to advanced topics
• Full playback control: previous/next step, auto-play, speed adjustment, and scrubbing
• Multilingual: Simplified Chinese, English, and more
