  2. Substring - Wikipedia

    en.wikipedia.org/wiki/Substring

    A suffix can be seen as a special case of a substring. Example: The string nana is equal to a suffix (and substring and subsequence) of the string banana: banana |||| nana A suffix tree for a string is a trie data structure that represents all of its suffixes. Suffix trees have large numbers of applications in string algorithms.

  3. Suffix tree - Wikipedia

    en.wikipedia.org/wiki/Suffix_tree

    Suffix tree for the text BANANA. Each substring is terminated with special character $. The six paths from the root to the leaves (shown as boxes) correspond to the six suffixes A$, NA$, ANA$, NANA$, ANANA$ and BANANA$. The numbers in the leaves give the start position of the corresponding suffix.

  4. Longest common substring - Wikipedia

    en.wikipedia.org/wiki/Longest_common_substring

    Building the suffix tree takes () time (if the size of the alphabet is constant). If the tree is traversed from the bottom up with a bit vector telling which strings are seen below each node, the k-common substring problem can be solved in Θ ( N K ) {\displaystyle \Theta (NK)} time.

  5. Longest repeated substring problem - Wikipedia

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

    In computer science, the longest repeated substring problem is the problem of finding the longest substring of a string that occurs at least twice. This problem can be solved in linear time and space Θ ( n ) {\displaystyle \Theta (n)} by building a suffix tree for the string (with a special end-of-string symbol like '$' appended), and finding ...

  6. Generalized suffix tree - Wikipedia

    en.wikipedia.org/wiki/Generalized_suffix_tree

    An alternative to building a generalized suffix tree is to concatenate the strings, and build a regular suffix tree or suffix array for the resulting string. When hits are evaluated after a search, global positions are mapped into documents and local positions with some algorithm and/or data structure, such as a binary search in the starting ...

  7. Substring index - Wikipedia

    en.wikipedia.org/wiki/Substring_index

    The suffix array, a sorted array of the starting positions of suffixes of the string, allowing substring search to be performed by binary search [1] [3] Augmenting a suffix array with an LCP array of the lengths of common prefixes of consecutive suffixes allows the search to be performed symbol-by-symbol, matching the search time of the suffix ...

  9. LCP array - Wikipedia

    en.wikipedia.org/wiki/LCP_array

    In computer science, the longest common prefix array (LCP array) is an auxiliary data structure to the suffix array.It stores the lengths of the longest common prefixes (LCPs) between all pairs of consecutive suffixes in a sorted suffix array.
