A string-matching algorithm wants to find the starting index m in string S[] that matches the search word W[]. The most straightforward algorithm, known as the "Brute-force" or "Naive" algorithm, is to look for a word match at each index m, i.e. the position in the string being searched that corresponds to the character S[m]. At each position m the algorithm first checks for equality of the first characte… WebDec 10, 2011 · The KMP matching algorithm is based on finite automata and works by implicitly building the transition table for an automaton that matches the string.
