Did I miss some basic `char` arithmetics?

  • 0

    it looks like in the inner if loop, even when the two characters are different, the character isn't being added to the char

    i ended up using a char[] instead and it was accepted(not a very efficient solution, only beating 40% of submissions), but still bugged by this..

    public class Solution {
        public char findTheDifference(String s, String t) {
            char[] sArr = s.toCharArray();
            char[] tArr = t.toCharArray();
            char ans = ' ';
            for(int i=0;i<tArr.length-1;i++){
                if(tArr[i] != sArr[i]){
                    return ans;
            return tArr[tArr.length-1];
