About This Course

Algorithms are the recipes of computer science — step-by-step procedures that transform input into output efficiently. They are the core of technical interviews, the foundation of system performance, and the reason some apps feel instant while others crawl.

This course covers every major algorithm category: sorting, searching, recursion, dynamic programming, and graph algorithms. Each algorithm is taught with intuition first (how would a human solve this?), then formalized, then implemented in Python with full Big O analysis. By the end, you'll be able to analyze any algorithm's complexity, choose the right approach for any problem, and confidently tackle coding interviews.
