String searching algorithm

String searching algorithms are used to find specific words, phrases, or patterns in large amounts of text. It is like a detective searching through a bunch of documents to find a specific clue. For example, if you are looking for the phrase "cat in the hat" in a book, the string searching algorithm can quickly find it for you. It does this by checking each letter of the text and seeing if it matches the letters in the phrase you are looking for. If it finds a match, it knows it has found the phrase and will stop searching.
