884 - Uncommon Words from Two Sentences.

Easy

A sentence is a string of single-space separated words where 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.

Given two sentences s1 and s2, return a list of all the uncommon words. You may return the answer in any order.

Example 1:

Input: s1 = “this apple is sweet”, s2 = “this apple is sour”

Output: [“sweet”,“sour”]

Example 2:

Input: s1 = “apple apple”, s2 = “banana”

Output: [“banana”]

Constraints:

  • 1 <= s1.length, s2.length <= 200
  • s1 and s2 consist of lowercase English letters and spaces.
  • s1 and s2 do not have leading or trailing spaces.
  • All the words in s1 and s2 are separated by a single space.
