An indepth explanation of the Knuth-Morris-Pratt algorithm

WebThe Knuth-Morris-Pratt (KMP) algorithm is a string matching algorithm that is used to find the occurrence(s) of a pattern within a larger text or string. It uses a pre-processing step to construct a partial match table, which is used to skip over previously matched characters in the text without starting from the beginning of the pattern again. WebMay 28, 1997 · All of the major exact string algorithms are covered, including Knuth-Morris-Pratt, Boyer-Moore, Aho-Corasick and the focus of the book, suffix trees for the much harder probem of finding all repeated substrings of a given string in linear time. In addition to exact string matching, there are extensive discussions of inexact matching. high speed training first aid at work
