String Matching

String matching is the process of finding a specific sequence of characters, called a pattern, within a larger body of text or data. Think of it like searching for a word or phrase within a document or a line of code. Algorithms designed for string matching efficiently scan through the text to identify whether the pattern appears, and if so, where. This technique is fundamental in various applications such as text editing, search engines, DNA analysis, and data validation, ensuring quick and accurate identification of needed information within sizable datasets.
