XOR Strings 3 HackerRank Problem Solutions

I will Provide solution in Multiple programming languages for you. If you are not able to find the code in required language then please share in comments so that our team can help you.

Problem Solution in Java 7

 public static String stringsXOR(String s, String t) {
        String res = new String("");
        for(int i = 0; i < s.length(); i++) {
            if(s.charAt(i) == t.charAt(i))
                res += "0";
                res += "1";

        return res;

Problem Solution in Python

def strings_xor(s, t):
    res = ""
    for i in range(len(s)):
        if s[i] == t[i]:
            res += '0';
            res += '1';

    return res

s = input()
t = input()
print(strings_xor(s, t))

Note: XOR String Implementation is possible in only few languages please chose only those languages else you will get errors. Also do not copy the code as the task is just to debug so just try debugging.
