Problem 88. It dseon't mettar waht oedrr the lrettes in a wrod are.
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.
