string matching

**string matching**

String matching is a fundamental concept in computer science and programming that involves finding occurrences of a substring within a larger string. It is widely used in text processing, search engines, data retrieval, and pattern recognition. Various algorithms-such as the Knuth-Morris-Pratt (KMP), Boyer-Moore, and Rabin-Karp-are designed to efficiently perform string matching, optimizing both speed and accuracy. This tag covers topics related to these algorithms, practical applications, and coding techniques for effective string comparison and search operations.
