  2. Lexicographic order - Wikipedia

    en.wikipedia.org/wiki/Lexicographic_order

    Then, sorting a subset of is equivalent to convert it into an increasing sequence. The lexicographic order on the resulting sequences induces thus an order on the subsets, which is also called the lexicographical order. In this context, one generally prefer to sort first the subsets by cardinality, such as in the shortlex order. Therefore, in ...

  4. Alphabetical order - Wikipedia

    en.wikipedia.org/wiki/Alphabetical_order

    In mathematics, lexicographical order is a means of ordering sequences in a manner analogous to that used to produce alphabetical order. [16] Some computer applications use a version of alphabetical order that can be achieved using a very simple algorithm, based purely on the ASCII or Unicode codes for characters. This may have non-standard ...

  5. Sorting - Wikipedia

    en.wikipedia.org/wiki/Sorting

    Such a component or property is called a sort key. For example, the items are books, the sort key is the title, subject or author, and the order is alphabetical. A new sort key can be created from two or more sort keys by lexicographical order. The first is then called the primary sort key, the second the secondary sort key, etc.

  6. Sorting algorithm - Wikipedia

    en.wikipedia.org/wiki/Sorting_algorithm

    Radix sort is an algorithm that sorts numbers by processing individual digits. n numbers consisting of k digits each are sorted in O(n · k) time. Radix sort can process digits of each number either starting from the least significant digit (LSD) or starting from the most significant digit (MSD). The LSD algorithm first sorts the list by the ...

  7. Suffix array - Wikipedia

    en.wikipedia.org/wiki/Suffix_array

    Suffix arrays are closely related to suffix trees: . Suffix arrays can be constructed by performing a depth-first traversal of a suffix tree. The suffix array corresponds to the leaf-labels given in the order in which these are visited during the traversal, if edges are visited in the lexicographical order of their first character.

  8. List of titles - Wikipedia

    en.wikipedia.org/wiki/List_of_titles

    This is a list of personal titles arranged in a sortable table. They can be sorted: Alphabetically; By language, nation, or tradition of origin; By function. See Separation of duties for a description of the Executive, Judicial, and Legislative functions as they are generally understood today.

  9. Three-way comparison - Wikipedia

    en.wikipedia.org/wiki/Three-way_comparison

    In C, the functions strcmp and memcmp perform a three-way comparison between strings and memory buffers, respectively. They return a negative number when the first argument is lexicographically smaller than the second, zero when the arguments are equal, and a positive number otherwise.
