Quicksort A sorting {algorithm} with O(n log n) average time {complexity}. One element, x of the list to be sorted is chosen and the other elements are split into those elements less than x and those greater than or equal to x. These two lists are then sorted {recursive}ly using the same algorithm until there is only one element in each list, at which point the sublists are recursively recombined in order yielding the sorted list. This can be written in {Haskell}: qsort :: Ord a => [a] -> [a] qsort [] = [] qsort (x:xs) = qsort [ u | u<-xs, u qsort [ u | u<-xs, u>=x ] [Mark Jones, Gofer prelude.] |
