Still broken in Ruby (no starter code)

For the java version.. only thing that make the exercise work is convert to Java 7 and you found all the function you need to modified.... please fix that for Java 8 and Java 15....

Solved using python

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

    return res

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

Hi Guys, please use JAVA 7 as env. It is working. In java 7 we have code already it is dubugging problem just need to change 3 things in the code given.

The problem specify debug the code, but for JavaScript, there is no code. Here my solution for JavaScript, not working despite solution is correct 🤷‍♂️ (I guess is because it does not have anything to compare lol)

process.stdin.resume();
process.stdin.setEncoding("ascii");
var input = "";
process.stdin.on("data", function (chunk) {
    input += chunk;
});
process.stdin.on("end", function () {
    // now we can read/parse input
    const [s, t] = input.split("\n")
    let res = ""

    for (let i = 0; i < s.length; i++)
        res += +(s[i] !== t[i])

    console.log(res)
});
