  2. Trie - Wikipedia

    en.wikipedia.org/wiki/Trie

    Lexicographic sorting of a set of string keys can be implemented by building a trie for the given keys and traversing the tree in pre-order fashion; [26] this is also a form of radix sort. [27] Tries are also fundamental data structures for burstsort , which is notable for being the fastest string sorting algorithm as of 2007, [ 28 ...

  3. Levenshtein distance - Wikipedia

    en.wikipedia.org/wiki/Levenshtein_distance

    It is at least the absolute value of the difference of the sizes of the two strings. It is at most the length of the longer string. It is zero if and only if the strings are equal. If the strings have the same size, the Hamming distance is an upper bound on the Levenshtein distance. The Hamming distance is the number of positions at which the ...

  4. Suffix tree - Wikipedia

    en.wikipedia.org/wiki/Suffix_tree

    A suffix tree for a string of length can be built in () time, if the letters come from an alphabet of integers in a polynomial range (in particular, this is true for constant-sized alphabets). [9] For larger alphabets, the running time is dominated by first sorting the letters to bring them into a range of size O ( n ) {\displaystyle O(n)} ; in ...

  5. C Sharp syntax - Wikipedia

    en.wikipedia.org/wiki/C_Sharp_syntax

    Whether it is a console or a graphical interface application, the program must have an entry point of some sort. The entry point of the C# application is the method called Main. There can only be one, and it is a static method in a class. The method usually returns void and is passed command-line arguments as an array of strings.

  6. HAT-trie - Wikipedia

    en.wikipedia.org/wiki/HAT-trie

    The hash bucket becomes the new root of the trie. The key strings are stored in the array nodes with a length encoding byte prefixed to the key value bytes. The value associated with each key can be stored either in-line alternating with the key strings, or placed in a second array, e.g., memory immediately after and joined to the array node. [4]

  7. Rope (data structure) - Wikipedia

    en.wikipedia.org/wiki/Rope_(data_structure)

    Rope (data structure) A simple rope built on the string of "Hello_my_name_is_Simon". In computer programming, a rope, or cord, is a data structure composed of smaller strings that is used to efficiently store and manipulate longer strings or entire texts. For example, a text editing program may use a rope to represent the text being edited, so ...

  8. Radix sort - Wikipedia

    en.wikipedia.org/wiki/Radix_sort

    Radix sort. O (w ⋅ n) {\displaystyle O (w\cdot n)} , where n {\displaystyle n} is the number of keys, and w {\displaystyle w} is the key length. In computer science, radix sort is a non- comparative sorting algorithm. It avoids comparison by creating and distributing elements into buckets according to their radix.

  9. Sorting algorithm - Wikipedia

    en.wikipedia.org/wiki/Sorting_algorithm

    Best, worst and average case behavior in terms of the size of the list. For typical serial sorting algorithms, good behavior is O(n log n), with parallel sort in O(log 2 n), and bad behavior is O(n 2). Ideal behavior for a serial sort is O(n), but this is not possible in the average case. Optimal parallel sorting is O(log n).
