WebThe Knuth-Morris-Pratt (KMP) algorithm is a string-matching algorithm that is used to find a pattern within a larger text string. It works by pre-computing a prefix function of the pattern, which is used to skip comparisons that are guaranteed to fail. This makes the algorithm more efficient than simple approaches such as brute force.
