C guarantees that all these character codes are positive
numbers, but says nothing about their values or their relative
order. Thus, your question is not answerable except in fairly
broad terms: "No fewer than zero and no more than fifteen."

If you want to impress your instructor with the depth of
your understanding, there's no better way to do it than to
submit an answer like the one above. At one stroke it shows
that you have mastered the material even better than your
teacher has, by pointing up a flaw in the homework assignment.
Since teachers are strongly interested in the increase of
knowledge and wisdom, you can expect to be thanked and suitably
rewarded. Good luck!

One - 'O' is the only letter that looks the same when inverted.

You missed S. Also, T, M, and E can be inverted in particular ways that do
not change their appearance. (Whether this is true in a given font is
another matter - but that's the case for O too.)
