Finite Automata algorithm for Pattern Searching - GeeksforGeeks

WebA String Matching or String Algorithm in Computer Science is string or pattern recognition in a larger space finding similar strings. KMP Algorithm- data thus uses such string algorithms to improve the time taken to find and eliminate such pattern when searching and therefore called linear time complexity algorithm. 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… middle row typing test
