If we return 0 things
must we write return 0 or return ?
Also is not clear must we count returnings with 0 things?
Not clear 3: Can we take bottle with each returning?

from statement: " if you want to return to the plantation s !>! 0". So, we mustn't output anything if we just return to the plantation with empty hands.
