Introduction to String Matching Algorithms | Finite Automata & KMP Basics

In this video, we begin our journey into String Matching Algorithms, a core topic in Computer Science and Data Structures.

You will learn:
What string matching is and how it works
What happens when a pattern does not exist in a string
Why string matching is important in real-world applications
An introduction to Finite Automata and how it helps in pattern matching
The basics of prefixes, suffixes, and prefix tables (LPS) used in efficient algorithms like KMP

This video is designed for undergraduate students, beginners, and exam preparation, explained in a simple and intuitive way.

📌 In upcoming videos, we will study:

Finite Automata in detail
Prefix Table (LPS) construction step by step
Naive String Matching Algorithm
Rabin–Karp Algorithm
Knuth–Morris–Pratt (KMP) Algorithm with clear explanations and examples

📝 Homework questions are provided at the end of the video.
