Knuth-Morris-Pratt algorithm

The Knuth-Morris-Pratt (KMP) algorithm is an efficient method for searching a string (the "needle") within another string (the "haystack"). It improves on straightforward searching by avoiding unnecessary comparisons. KMP first preprocesses the needle to create a table that indicates how far to shift the search position when a mismatch occurs. This way, it can skip ahead rather than starting over from scratch, significantly speeding up the search process, especially in larger texts. As a result, KMP is particularly useful in applications like text processing, searching databases, and implementing features in text editors.
