A simple and inefficient way to see where one string occurs inside another is to check at each index, one by one. First, we see if there is a copy of the needle starting at the first character of the haystack; if not, we look to see if there's a copy of the needle starting at the second character of the haystack, and so forth.
A template to find the numeric position of first appearance of ''sub_string'' in ''text'' Template parameters [Edit template data] Parameter Description Type Status Text 1 The text to search within String required Sub_string 2 The string to be searched within the text String required See also
This is the {{Str startswith}} meta-template.. It returns "yes" if the second parameter is the start of the first parameter. Both parameters are trimmed before use. Examples
P denotes the string to be searched for, called the pattern. Its length is m. S[i] denotes the character at index i of string S, counting from 1. S[i..j] denotes the substring of string S starting at index i and ending at j, inclusive. A prefix of S is a substring S[1..i] for some i in range [1, l], where l is the length of S.
Among them are suffix trees, [5] metric trees [6] and n-gram methods. [ 7 ] [ 8 ] A detailed survey of indexing techniques that allows one to find an arbitrary substring in a text is given by Navarro et al. [ 7 ] A computational survey of dictionary methods (i.e., methods that permit finding all dictionary words that approximately match a ...

In computer science, the Knuth–Morris–Pratt algorithm (or KMP algorithm) is a string-searching algorithm that searches for occurrences of a "word" W within a main "text string" S by employing the observation that when a mismatch occurs, the word itself embodies sufficient information to determine where the next match could begin, thus bypassing re-examination of previously matched characters.
