WebDec 20, 2024 · In this post we will discuss a more efficient algorithm solving this problem - the Knuth-Morris-Pratt (KMP) algorithm. The Knuth-Morris-Pratt algorithm. Obviously, the substring search algorithm has to somehow compare both strings character-after-character. Suppose we are scanning the string from left to right and we found b 0 b_0 b 0 . WebDec 13, 2024 · The Knuth-Morris-Pratt algorithm. The task is the classical application of the prefix function. Given a text t and a string s , we want to find and display the positions of all occurrences of the string s in the text t . For convenience we denote with n the length of the string s and with m the length of the text t .
