algo-vision

Easily visualize and practice Data Structures and Algorithms (DSA). Starting with dynamic programming, we also support bit manipulation, binary search, and more.

Quick Start

Visit algo-lens to explore algorithm visualizations.

What’s Inside

  • Dynamic Programming: See step-by-step visualizations to understand how solutions are built.
  • Bit Manipulation and Binary Search: Visualize and practice these techniques.
  • Interactive Tools: Experiment with algorithms to learn how they work.
  • More to Come: New algorithms are added regularly.
