About this app

Algo Demo — Visualize Algorithms & Data Structures
Designed for CS students, interview preppers, and educators, Algo Demo demystifies algorithms through interactive animations and step-by-step visualizations.

Covered Topics:
• Data Structures: Linked Lists, Binary Trees, Stacks, Hash Tables
• Core Algorithms: Sorting, Two Pointers, Dynamic Programming, Binary Search

Key Features:
• 🎬 All-New Progress Control: Our most powerful interactive upgrade yet! Drag a sleek progress bar to jump to any step of an algorithm in real-time. Perfect your understanding by replaying complex parts at your own pace.
• 💻 Live Code Playback: Watch the code execute in perfect sync with the visualization. Key lines are highlighted as the algorithm runs, forging a clear connection between abstract logic and concrete implementation.
• Smooth Animations: Break down each step of algorithm execution with crystal-clear visuals.
• Interactive Playback: Adjust speed, pause, or rewind for deeper learning.
