result = ajs_random_sort(input [, min=min] [, max=max] [, seed=seed])

Return random indices, or sort an array into random order

ajs_random_sort(n) returns a random permutation of the integers 0 to (n - 1)

ajs_random_sort(n, min=min, max=max) returns n (different) random integers between min and (max - 1)

ajs_random_sort(array) returns the elements of array in a random order

input in required: Either (1) A single integer giving the number of array indices to return or (2) an input array to be sorted into random order

min in optional default=0: Used with a single integer input, this is the minimum array index that may be returned.
max in optional default=input: Used with a single integer input, this number ** - 1 ** is the maximum array index that may be returned.
seed in optional: Seed for randomu
