1/**
2 * [389] Find the Difference
3 *
4 * You are given two strings s and t.
5 * String t is generated by random shuffling string s and then add one more letter at a random position.
6 * Return the letter that was added to t.
7 *  
8 * Example 1:
9 * 
10 * Input: s = "abcd", t = "abcde"
11 * Output: "e"
12 * Explanation: 'e' is the letter that was added.

14 * Example 2:
15 * 
16 * Input: s = "", t = "y"
17 * Output: "y"
18 * 
19 *  
20 * Constraints:
21 * 
22 * 	0 <= s.length <= 1000
23 * 	t.length == s.length + 1
24 * 	s and t consist of lowercase English letters.
