{{Sorting Algorithm}} ;Task: [[wp:Bogosort|Bogosort]] a list of numbers. Bogosort simply shuffles a collection randomly until it is sorted. "Bogosort" is a perversely inefficient algorithm only used as an in-joke. Its average run-time is   O(n!)   because the chance that any given shuffle of a set will end up in sorted order is about one in   ''n''   factorial,   and the worst case is infinite since there's no guarantee that a random shuffling will ever produce a sorted sequence. Its best case is   O(n)   since a single pass through the elements may suffice to order them. Pseudocode: '''while not''' InOrder(list) '''do''' Shuffle(list) '''done'''
The [[Knuth shuffle]] may be used to implement the shuffle part of this algorithm.
