First, length of numbers is 100. So you can not take input in form of int or even long long int.
HINT: use string to take input.

Here is my solution (try coding it yourself first):

#include
using namespace std;
int main() {
int T;
cin>>T;
while(T–)
{
string x,y;
cin>>x>>y;
for(int i=0;i<x.size();i++)
if(x[i]==y[i])
x[i]=‘0’;
else
x[i]=‘1’;
cout<<x<<endl;
}
}
