From The Free On-line Dictionary of Computing (30 December 2018) :

  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 recursively 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=x ]
  
     [Mark Jones, Gofer prelude.]
