-/**
- * 884. Uncommon Words from Two Sentences
- *
- * We are given two sentences A and B.  (A sentence is a string of space separated words.  Each word consists only of lowercase letters.)
- *
- * A word is uncommon if it appears exactly once in one of the sentences, and does not appear in the other sentence.
- *
- * Return a list of all uncommon words.
- *
- * You may return the list in any order.
- *
- *
- *
- * Example 1:
- *
- * Input: A = "this apple is sweet", B = "this apple is sour"
- * Output: ["sweet","sour"]
- * Example 2:
- *
- * Input: A = "apple apple", B = "banana"
- * Output: ["banana"]
- *
- *
- * Note:
- *
- * 0 <= A.length <= 200
- * 0 <= B.length <= 200
- * A and B both contain only spaces and lowercase letters.
