    This is a matter of opinion. In my opinion, I'd always select the first option as the intent of the code is clearer: check length of the arrays, then check the lengths of the elements. But that is just opinion: there's no right answer to this. Commented Sep 21, 2018 at 8:43

    If the specification is "if the array lengths are unequal the answer is always FALSE", then checking boundaries over and over within the loop would be both wasteful and less readable. I see no upside to Style 2. Commented Sep 21, 2018 at 10:28
