  2. Longest palindromic substring - Wikipedia

    en.wikipedia.org/wiki/Longest_palindromic_substring

    Since the palindrome at the MirroredCenter is "aba" and extends beyond the boundaries of the "Old" palindrome, we know the longest palindrome at the second "b" can only extend up to the border of the "Old" palindrome. We know this because if the character after the "Old" palindrome had been an "a" instead of a "c", the "Old" palindrome would ...

  3. Palindrome tree - Wikipedia

    en.wikipedia.org/wiki/Palindrome_Tree

    In computer science a palindrome tree, also called an EerTree, [1] is a type of search tree, that allows for fast access to all palindromes contained in a string.They can be used to solve the longest palindromic substring, the k-factorization problem [2] (can a given string be divided into exactly k palindromes), palindromic length of a string [3] (what is the minimum number of palindromes ...

  4. Suffix tree - Wikipedia

    en.wikipedia.org/wiki/Suffix_tree

    Find the longest common substrings to at least strings in for =, …, in () time. [23] Find the longest palindromic substring of a given string (using the generalized suffix tree of the string and its reverse) in linear time. [24]

  5. Longest common substring - Wikipedia

    en.wikipedia.org/wiki/Longest_common_substring

    In computer science, a longest common substring of two or more strings is a longest string that is a substring of all of them. There may be more than one longest common substring. Applications include data deduplication and plagiarism detection.

  6. Palindrome - Wikipedia

    en.wikipedia.org/wiki/Palindrome

    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

  7. Longest repeated substring problem - Wikipedia

    en.wikipedia.org/wiki/Longest_repeated_substring...

    The string spelled by the edges from the root to such a node is a longest repeated substring. The problem of finding the longest substring with at least k {\displaystyle k} occurrences can be solved by first preprocessing the tree to count the number of leaf descendants for each internal node, and then finding the deepest node with at least k ...

  8. String-searching algorithm - Wikipedia

    en.wikipedia.org/wiki/String-searching_algorithm

    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.

  9. Ternary search tree - Wikipedia

    en.wikipedia.org/wiki/Ternary_search_tree

    Many implementations make use of an end of string character to ensure only the latter case occurs. The path is then deleted from firstMid.mid to the end of the search path. In the case that firstMid is the root, the key string must have been the last string in the tree, and thus the root is set to null after the deletion.
