string searching

String searching involves finding a specific sequence of characters (called a "substring") within a larger body of text or data. Imagine looking for a word or phrase inside a document; string searching algorithms efficiently examine the text to locate where the substring appears, if at all. They do this by comparing portions of the text to the target pattern, often using strategies that minimize unnecessary comparisons. This process is fundamental in tasks like text editing, search engines, and data analysis, enabling quick and accurate identification of specific information within larger sets of text.
