О чём код?
// 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: // e // Explanation: // 'e' is the letter that was added. public class FindTheDifference { public char findTheDifference(String s, String t) { int charCodeS = 0; int charCodeT = 0; for(int i = 0; i < s.length(); i++) { charCodeS += (int)(s.charAt(i)); } for(int i = 0; i < t.length(); i++) { charCodeT += (int)(t.charAt(i)); } return (char)(charCodeT - charCodeS); } }
