Data Structures and Algorithms

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
