C# implementation:

static string strings_xor(string s, string t)
{
    string result = "";

    for(int i = 0; i < s.Length; i++)
    {

        result += s[i] == t[i] ? '0' : '1';
    }

    return result;
}

Compiler is saying "Wrong Answer".

include

using namespace std;

string strings_xor(string s, string t) {

string res = "";
for(int i = 0; i < s.length(); i++) {
    if(s[i] == t[i])
        res.push_back('0');
    else
        res.push_back('1');
}
return res;

}

int main() { string s, t; cin >> s >> t; cout << strings_xor(s, t) << endl; return 0; } ** still the compiler is saying "Wrong Answer"

the

Here is my Python solution!

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))

Here is my c++ working solution, you can watch the explanation here : https://youtu.be/eCWFW0phR-4.

Keep in mind that it's not just about getting the right answer, it's also about making at most three changes, so an extra space on a new line will cause your code to fail, you can get a demo in the video above.

string strings_xor(string s, string t) {

    string res = "";
    for(int i = 0; i < s.size(); i++) {
        if(s[i] == t[i])
            res += '0';
        else
            res += '1';
    }

    return res;
}

Hello, I am solving this with one line of code on JS. I am a new coder so I may be wrong somewhere. I am achieving the correct result in std.out but when i run the test is not passing me. Please let me know if i am missing anything?

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 console.log(Number(input.split("\n")[0]) ^ Number(input.split("\n")[1])); });
