Put more test cases in. Makes cheating too tempting.
the regexp solution is great
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.
