One application for stable sorting algorithms is sorting a list using a primary and secondary key. For example, suppose we wish to sort a hand of cards such that the suits are in the order clubs (♣), diamonds (♦), hearts (♥), spades (♠), and within each suit, the cards are sorted by rank. This can be done by first sorting the cards by ...
An example of a list that proves this point is the list (2,3,4,5,1), which would only need to go through one pass of cocktail sort to become sorted, but if using an ascending bubble sort would take four passes. However one cocktail sort pass should be counted as two bubble sort passes. Typically cocktail sort is less than two times faster than ...

In mathematics, the Fibonacci sequence is a sequence in which each number is the sum of the two preceding ones. Numbers that are part of the Fibonacci sequence are known as Fibonacci numbers, commonly denoted Fn . Many writers begin the sequence with 0 and 1, although some authors start it from 1 and 1 [1][2] and some (as did Fibonacci) from 1 ...

Block sort. Block sort stably sorting numbers 1 to 16. Insertion sort groups of 16, extract two internal buffers, tag the A blocks (of size √ 16 = 4 each), roll the A blocks through B, locally merge them, sort the second buffer, and redistribute the buffers. Block sort, or block merge sort, is a sorting algorithm combining at least two merge ...
Worst-case space complexity. O ( 1 ) {\displaystyle O (1)} Comb sort is a relatively simple sorting algorithm originally designed by Włodzimierz Dobosiewicz and Artur Borowy in 1980, [1][2] later rediscovered (and given the name "Combsort") by Stephen Lacey and Richard Box in 1991. [3] Comb sort improves on bubble sort in the same way that ...
