Extra randomized functions on lists.
choose : List a -> Random.Generator ( Maybe a, List a )
Sample without replacement: produce a randomly selected element of the
list, and the list with that element omitted. If the list is empty, the
selected element will be Nothing
.
shuffle : List a -> Random.Generator (List a)
Shuffle the list. Takes O(n log n) time and no extra space.
choices : Basics.Int -> List a -> Random.Generator ( List a, List a )
Repeated sample without replacement: produce a list of randomly selected elements of some list, and the list of unselected elements.
