AlgoNote: Algorithm Visualizer

Stop memorizing — start understanding.

AlgoNote visualizes algorithms and data structures with step-by-step animations, helping you prepare for coding interviews more effectively.

■ Key Features
▶ Logic Visualization
Watch code execution as animations.
See variable changes and memory states in real time.

▶ Time Control
Rewind, pause, and adjust speed freely.
Analyze the state at any point in execution.

▶ Deep Understanding
Learn the principles, not just the patterns.
Understand why algorithms work from the ground up.
