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.
String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).. Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.

The C and Java implementations below have a space complexity (make_delta1, makeCharTable). This is the same as the original delta1 and the BMH bad-character table . This table maps a character at position i {\displaystyle i} to shift by len ( p ) − 1 − i {\displaystyle \operatorname {len} (p)-1-i} , with the last ...
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.

Matches the ending position of the string or the position just before a string-ending newline. In line-based tools, it matches the ending position of any line. ( ) Defines a marked subexpression, also called a capturing group, which is essential for extracting the desired part of the text (See also the next entry, \n). BRE mode requires \( \). \n
