 📘 DATA STRUCTURES – COMPLETE NOTES (For Students) 🔹 Introduction to Data Structures A Data Structure is a method of organizing, storing, and managing data in a computer so that it can be accessed and modified efficiently. Data structures are very important in computer science because they help in efficient data processing and problem solving. 🔹 Why Data Structures are Important? Efficient data storage Faster data access Better memory utilization Easy data manipulation Improves program performance Foundation for algorithms and software development 🔹 Types of Data Structures Data structures are mainly classified into two types: 1. Primitive Data Structures These are basic data types. Integer Float Character Double Example: Copy code C int x = 10; 2. Non-Primitive Data Structures These are further divided into: a) Linear Data Structures Array Stack Queue Linked List b) Non-Linear Data Structures Tree Graph 🔹 ARRAY An array is a collection of elements of the same data type, store...
