  2. Longest palindromic substring - Wikipedia

    en.wikipedia.org/wiki/Longest_palindromic_substring

    It looks at each character as the center of a palindrome and loops to determine the largest palindrome with that center. The loop at the center of the function only works for palindromes where the length is an odd number. The function works for even-length palindromes by modifying the input string.

  3. String (computer science) - Wikipedia

    en.wikipedia.org/wiki/String_(computer_science)

    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.

  4. String-searching algorithm - Wikipedia

    en.wikipedia.org/wiki/String-searching_algorithm

    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.

  5. Template:Str find word - Wikipedia

    en.wikipedia.org/wiki/Template:Str_find_word

    It is possible to check multiple words against the source wordlist. AND-words to check |andwords=: can have a wordlist (comma-separated as |source= is). Each word will be checked against the source. When all and-words are found, the return value is True. {{Str find word |source=alpha, beta, gamma, foo, bar |andwords=alpha, foo}} (True) → ...

    en.wikipedia.org/wiki/Help:Searching/Features

    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

  7. ROT13 - Wikipedia

    en.wikipedia.org/wiki/ROT13

    Some words will, when transformed with ROT13, produce another word. Examples of 7-letter pairs in the English language are abjurer and nowhere, and Chechen and purpura. Other examples of words like these are shown in the table. [12] The pair gnat and tang is an example of words that are both ROT13 reciprocals and reversals.

  8. Suffix tree - Wikipedia

    en.wikipedia.org/wiki/Suffix_tree

    The total length of all the strings on all of the edges in the tree is (), but each edge can be stored as the position and length of a substring of S, giving a total space usage of () computer words. The worst-case space usage of a suffix tree is seen with a fibonacci word , giving the full 2 n {\displaystyle 2n} nodes.
