Clicking on the up/down arrows in a column header will sort the column; clicking again will reverse the sort. Text is sorted alphabetically. Numbers are sorted numerically. Mixed data is sorted alphabetically. For advanced sort options, see Help:Sorting
Merge sort. In computer science, a sorting algorithm is an algorithm that puts elements of a list into an order.The most frequently used orders are numerical order and lexicographical order, and either ascending or descending.
In mathematics and computer science, the sorting numbers are a sequence of numbers introduced in 1950 by Hugo Steinhaus for the analysis of comparison sort algorithms. These numbers give the worst-case number of comparisons used by both binary insertion sort and merge sort. However, there are other algorithms that use fewer comparisons.
Text breaks default numerical sorting if it is before or after a number in one of the first 5 cells in a column. A colon by itself (to signify no data, for example) in one of the first 5 cells in a column breaks numerical sorting. Even when using data-sort-type=number in the column header, text in front of a number in any cell breaks numerical ...
Additionally, using a power of two near n as the radix allows the keys for each pass to be computed quickly using only fast binary shift and mask operations. With these choices, and with pigeonhole sort or counting sort as the base algorithm, the radix sorting algorithm can sort n data items having keys in the range from 0 to K − 1 in time O ...
Adding data-sort-type="number" to the relevant column header solves many numerical sorting problems. See Help:Sortable tables § Forcing a column to have a particular data type . This template can be useful when building a sortable table in which a column contains both numbers and text.
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.
The following is a bitonic sorting network with 16 inputs: The 16 numbers enter as the inputs at the left end, slide along each of the 16 horizontal wires, and exit at the outputs at the right end. The network is designed to sort the elements, with the largest number at the bottom. The arrows are comparators.
