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.
