• question on result being shorter

Question related to mission Auto Painting

 

For the chickio(3,2) I get this back:

===========================================

Your result: "01,20,21,"

It can be shorter.

Is it just the trailing comma or is my solution really a longer one than the shortest possible? From the examples in the problem I think my output is different but not incorrect.
