Each set contains characters

like

first letter from first set and second number from second set. like that.
there is a possibility of n number of sets and set are independent.

By saying that you shouldn't have any answer.

what you are trying to do here is not a permutation (at least after looking at your demanded output)

(maybe that's why you corrected yourself and post second topic)
