Hey,
I'm having some trouble in finding a solution for this problem. Which is:
I need a function that given an array with a number of elements n, and a positive integer k <= n, returns the next k-permutation of the array.
For example if k=2, the array (1,2,3) would have the following permutations:
1 2
1 3
2 1
2 3
3 1
3 2
I am not sure if they would be generated in this order, but that's not relevant as long as there are no repetitions.
Thankyou
Regards,
