Words Only Once
When comparing two texts, you may need to find words that appear in only one place and nowhere else. Write a function uncommon_words that receives two space-separated sentences, s1 and s2. A word is uncommon if it appears exactly once in one sentence and does not appear in the other sentence at all. Return the uncommon words sorted alphabetically.
