nextperm

Outputs the next permutation of the ordered tuple x.

Description

Using lexical order on the set {1, 2, ..., N}, outputs the next permutation of the ordered tuple x. You have exhausted the list when All(nextperm(x,N) == x) is TRUE.

For example
   nextperm([1 5 4], 5) returns [2 1 3]
   nextperm([2 1 3], 5) returns [2 1 4]
   nextperm([5 4 3], 5) returns [5 4 3]

I don't know how to edit my own submission. The description should read "Using lexical order on the set {1, 2, ..., N}...".
