Data Structures and Algorithms (DSA) form the foundation of computer science. Understanding DSA helps you write clean, efficient, and scalable code. This guide breaks down complex concepts into simple, digestible pieces. 1. Introduction to Core Concepts What is a Data Structure? A specialized format for organizing data. A way to store and manage information. A tool to enable efficient data access. Examples include arrays, lists, and trees. What is an Algorithm? A step-by-step set of instructions. A clear procedure to solve a problem. A method to process input into output. Examples include sorting and searching techniques. 2. Understanding Algorithm Efficiency (Big O Notation)
