Given two strings s and t which consist of only lowercase letters.
String t is generated by random shuffling string s and then add one more letter at a random position.
Find the letter that was added in t.
Example:
Input:s = "abcd"t = "abcde"Output:eExplanation:'e' is the letter that was added.class Solution {public: char findTheDifference(string s, string t) { int table1[26] = {0}; int table2[26] = {0}; for(int i = 0; i < s.length(); ++i) table1[s[i] - 'a']++; for(int i = 0; i < t.length(); ++i) table2[t[i] - 'a']++; for(int i = 0; i < 26; ++i){ if(table1[i] != table2[i]) return i + 'a'; } }};新聞熱點(diǎn)
