## What is Algo Viewer?

AlgoViewer helps you understand algorithms the way they were meant to be understood — by watching them work, step by step.

Whether you're a CS student studying for exams, a developer preparing for technical interviews, or just someone curious about how sorting, searching, and graph traversal actually work, this app breaks it down visually so it clicks.

WHAT'S INSIDE

34 algorithms across 6 categories:

• Search — Linear Search, Binary Search, Interpolation Search
• Sorting — Bubble, Selection, Insertion, Merge, Heap, Quick, Radix
• Linear Data Structures — Stack, Queue, Linked List, Doubly Linked List, Circular Linked List
• Non-Linear Data Structures — Binary Tree, BST, Heap, Hash Table
• Graphs — BFS, DFS, Dijkstra, Prim, Kruskal, Bellman-Ford, Floyd-Warshall
• Math — Factorial, Fibonacci, GCD, Sieve of Eratosthenes, Prime Factorization, Fast Exponentiation, LCM, Catalan Numbers

HOW IT WORKS

1. Pick an algorithm
2. Set your own input data or use a preset
3. Tap play and watch each step unfold with clear, color-coded animations
4. Read the detailed explanation to understand the "why" behind each step
5. Check out the code — every algorithm includes examples in Swift, Python, and Java

BUILT FOR LEARNING

• Step-by-step animations you can pause, rewind, and speed up
• Detailed explanations with complexity analysis and real-world use cases
• Code examples in 3 languages with copy support
• Time complexity charts so you can see how algorithms scale
• Light and dark mode
• Fully bilingual — complete English and Spanish support

NO ADS. NO SUBSCRIPTIONS.

One purchase. That's it. You get everything, including future updates with new algorithms and categories at no extra cost.

Built with care by a developer who believes the best way to learn an algorithm is to see it in action.
