## Description

AlgoPrep - Algos, DS Made Easy is a Chrome extension designed to help computer science students and software engineer interview candidates visualize how popular sorting and searching algorithms work in real time. Users can explore step-by-step animations of algorithms including bubble sort, quick sort, merge sort, binary search, and more. The extension also covers data structures such as stacks, linked lists, queues, trees, and graphs, with tree and graph traversal visualizations.

This tool offers insights into best, average, and worst-case time complexities, making it an excellent interactive learning aid beyond just reading pseudocode. Best of all, AlgoPrep works completely offline, enabling learning without an internet connection. Since its founding in 2017, it has been enhancing algorithm understanding through intuitive, visual demonstrations.
