🍱 Solution

class Solution {
    public char findTheDifference(String s, String t) {
       char c1[]=s.toCharArray();
        char c2[]=t.toCharArray();
        int i,j;
        Arrays.sort(c1);
        Arrays.sort(c2);
        for(i=0;i<s.length();i++){
            if(c1[i]!=c2[i]){
                return c2[i];
            }
        }
        return c2[t.length()-1];
    }
