The reverse of a string is a string with the same symbols but in reverse order. For example, if s = abc (where a, b, and c are symbols of the alphabet), then the reverse of s is cba. A string that is the reverse of itself (e.g., s = madam) is called a palindrome, which also includes the empty string and all strings of length 1.
Anadrome: a word or phrase that reads as a different word or phrase in reverse; Apronym: an acronym that is also a phrase pertaining to the original meaning RAS syndrome: repetition of a word by using it both as a word alone and as a part of the acronym; Recursive acronym: an acronym that has the acronym itself as one of its components
A string-searching algorithm, sometimes called string-matching algorithm, is an algorithm that searches a body of text for portions that match by pattern. A basic example of string searching is when the pattern and the searched text are arrays of elements of an alphabet ( finite set ) Σ.
Each word you see in a page's content (a title's content) is already in an index, where it points to all its other prearranged results. A word is indexed to a list of page names, where it is seen in the text, or it is seen in the title only. Each indexed word is seen as a string of alphabetic characters a-z, or; a string of digits 0-9, or
It is possible to find the longest palindromic substring of a given input string in linear time. [55] [56] The palindromic density of an infinite word w over an alphabet A is defined to be zero if only finitely many prefixes are palindromes; otherwise, letting the palindromic prefixes be of lengths n k for k=1,2,... we define the density to be
Applications of reverse word dictionaries include: Simple rhyming dictionaries, to the extent that spelling predicts pronunciation. Finding words with a given suffix (i.e., meaningful ending), like -ment. Finding words with the same ending as a given word, even if the sequence is not meaningful.

A string s = abc, composed of zero or more characters of the alphabet (here, 'a', 'b', and 'c'), is said to be the reverse of string t if t = cba. For example, if Σ = {0,1} the string 0011001 is the reverse of 1001100. A string that is the reverse of itself is also called a palindrome, which includes the empty string and all strings of length 1.
