Description

The **Data Structures Full Notes PDF** is an extensive, well-organized academic guide designed for computer science students, engineering aspirants, and programming enthusiasts. This document covers every major concept of data structures—starting from fundamental definitions to advanced structures like binary trees, graphs, and algorithms—making it a one-stop resource for conceptual understanding and coding practice.

### 📘 Overview
This comprehensive guide introduces the **core concepts of data structures** including **arrays, linked lists, stacks, queues, trees, and graphs**. It explains each concept with clear definitions, diagrams, algorithms, and C programming examples. Whether you are preparing for exams, coding interviews, or brushing up on your programming foundations, this document delivers the clarity and depth needed to master data structure principles.

### 🧩 Key Topics Covered
1. **Introduction to Data Structures** – Basic terminology, need for data structures, and types (primitive vs non-primitive). Explains how data structures optimize time and space complexity for efficient computation.
2. **Classification of Data Structures** – Covers linear (arrays, stacks, queues, linked lists) and non-linear (trees, graphs) structures with examples and use cases.
3. **Arrays** – One-dimensional, two-dimensional, and multi-dimensional arrays, operations like insertion, deletion, traversal, searching, and sorting, including **sparse matrix representation** and memory layout.
4. **Linked Lists** – Single, double, circular, and header linked lists with memory representation. Step-by-step algorithms for **insertion, deletion, and traversal**. Includes C examples and visual illustrations.
5. **Stacks** – Concept of LIFO structure, stack operations (`push`, `pop`, `peek`), stack overflow and underflow conditions, and their implementation using arrays and linked lists. Includes **recursion and postfix/prefix evaluation (Polish Notation)**.
6. **Queues** – FIFO structure, types of queues (linear, circular, priority), enqueue and dequeue algorithms, and their **array and linked list implementations**. Includes **applications in CPU scheduling, printer queues, and process management**.
7. **Trees** – Introduction to hierarchical data representation, tree terminology, types (binary tree, binary search tree, expression tree), and **traversal techniques (in-order, pre-order, post-order)**. Explains **linked list representation, expression trees, and syntax trees** with examples.
8. **Graphs** – Covers **directed and undirected graphs**, terminology (vertices, edges, degree, path), representations (adjacency matrix and adjacency list), and **graph traversal techniques (BFS and DFS)**. Discusses **weighted and unweighted graphs** and practical applications in networks and social media.
9. **Algorithm Analysis** – Explains **time and space complexity**, **Big O notation**, and **trade-offs** in algorithm design.
10. **Applications of Data Structures** – Explains real-world applications such as file systems (trees), social networks (graphs), and operating system scheduling (queues and stacks).
