An internet meme from 2003 (read more here) asserted that readers are relatively insensitive to letter order in words, so long as the first and last letters are unchanged.
Given a string of words s, take each word in turn and reverse the order of letters 2 through n-1, where n is the length of the words. Non-alphabetic characters should remain in place.
So if
 sIn = 'hello'
then
 sOut = 'hlleo'
And if
 sIn = 'This is the first time I have used MATLAB.'
then
 sOut = 'Tihs is the fsrit tmie I hvae uesd MALTAB.'

Put more test cases in. Makes cheating too tempting.

Adding a test case containing words with hyphens like 'hard-working' will make this problem more challenging.

Needs more test cases. Some would fail with input sIn = 'what is a chain' because of the 'ha' occurring in the middle of both in 'what' and 'chain'. Also needs test cases with hyphened words.

interesting question

I thought the empty set test was uncalled for. Might as well add in numeric arguments if you're wanting to make a case for checking if your inputs are valid.
