KMP Algorithm (Part 1: Constructing LPS Array)

In this tutorial, we dive into the KMP Algorithm, a fundamental string matching technique in computer science known for its efficiency in searching substrings. This video focuses on the crucial first step of the KMP Algorithm: constructing the LPS (Longest Prefix Suffix) Array.

Key Features of the KMP Algorithm:

• Efficient Pattern Matching: KMP eliminates the need for unnecessary comparisons, significantly reducing the time complexity to O(n + m), where n is the length of the text and m is the length of the pattern.
• LPS Array Construction: Learn how the LPS array helps in determining the next positions to match, thus avoiding redundant checks.
• Foundation for Advanced Techniques: Understanding the LPS array is essential for grasping the full KMP Algorithm and its applications in complex string matching problems.
