    Many languages where there is no code should be hidden... if that a thing. And something's wrong with C++ grader?

    The C code is almost blank, just the main function and not the strings_xor function. So i had to create the code by myself so of course it doesn't work since the main condition isn't satisfied (just 3 lines)...

    C implementation : 

    #include <math.h>
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <assert.h>
#include <limits.h>
#include <stdbool.h>

char * strings_xor(char * input1, char * input2)
{
    char * answer = malloc(strlen(input1) * sizeof(char));
    
    for (int i = 0; i < strlen(answer); ++i)
    {
        answer[i] = '0';
    }
    
    // We read the console
    
    scanf("%s\n",input1);
    scanf("%s\n",input2);
    
    // We calculate the XOR relation between the inputs
    
    for (int i = 0; i < strlen(input1); ++i)
    {
        if (input1[i] != input2[i])
        {
            answer[i] = '1';
        }
        if (input1[i] == input2[i])
        {
            answer[i] = '0';
        }
    }
    
    return answer;
}

int main()
{
    // We create three pow(10,4)+1 length string variables to stock the inputs and to create the answer
    
    char * input1 = malloc((pow(10,4)+1) * sizeof(char));
    char * input2 = malloc((pow(10,4)+1) * sizeof(char));
    
    char * answer = strings_xor(input1,input2);
    
    // We display the answer
    
    printf("%s",answer);
    
    free(input1);
    free(input2);
    free(answer);
	`
    
    return 0;
}

    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"

    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))
