KMP Algorithm in Java 🔍 | Pattern Searching Tutorial (With User Input)

In this Java tutorial, we implement the Knuth–Morris–Pratt (KMP) Algorithm for fast string matching and pattern searching. 🚀 Unlike brute-force search, KMP uses a prefix-suffix table (LPS array) to efficiently skip characters, making it ideal for solving substring search problems. 📌 What this program does This Java program implements the Knuth–Morris–Pratt (KMP) Algorithm for string pattern searching. It finds all occurrences of a substring (pattern) inside a larger string (text) in linear time O(n+m), unlike brute force which can be O(n×m). This program also takes user input, so you can test your own text and patterns in real-time! 📌 Why is this program useful? Efficient searching: Handles long texts and patterns much faster than brute force. Practical applications: Search words in documents DNA sequence matching Plagiarism detection Search inside compilers/editors 📌 What you’ll learn in this video: *How the KMP Algorithm works step by step *Building the LPS (Longest Prefix Suffix) array *Efficient pattern searching in strings *Handling multiple matches in a text *Taking user input in Java for flexible testing If you enjoyed this video, LIKE 👍, COMMENT 💬, and SUBSCRIBE 🔔 for more Java tutorials on algorithms and data structures! #Java #KMP #StringMatching #algorithms #PatternSearching #codingforbeginners
