Introduction to Searching Algorithms

Searching is one of the most fundamental operations in software development, yet choosing the wrong approach can slow your application to a crawl. This text-based course helps you transition from writing basic loops to understanding efficient search algorithms and how data structures directly impact performance. What you'll learn: Learn the core concepts of searching and why data organization dictates algorithm speed. Implement linear search and binary search from scratch while comparing their efficiency. Analyze algorithmic performance using basic Big O notation to predict search times. Explore hash-based lookups and how modern key-value systems achieve near-instant results. Discover how database indexing and modern search patterns organize data for rapid retrieval. You will start with essential terminology and foundational definitions before moving step-by-step through search techniques, complete with clear code snippets and conceptual walkthroughs. This course is designed for beginner developers and computer science students looking to build a strong foundation in algorithmic thinking, with no prior search experience required.
