'How would you draw the NFA Language x*?

I am learning about automata, and we are now learning about NFAs, my professor told us to write an NFA for some language x*, as I understands * means that if you also have no input the language should be accepted, so when I made the NFA, in this case the start stage would also be the final stage my professor told me it is wrong because it would have any sense to make a automata that accepts on nothing, am I in the wrong here?

how about using quick-sort algorithm. And, I am not sure I got what your data looks like and what results you want to obtain. Maybe you could show us parts of your data frame.
