Ultra fast mathematician problem

#1

my code is giving wrong answer for one testcase but the code is right…
#include
using namespace std;
int main() {
int t;
cin>>t;
while(t>0)
{
int no1,no2,rem1=0,rem2=0;
cin>>no1>>no2;
int ans[100];
int i=0;
while(no1>0||no2>0)
{
rem1=no1%10;
rem2=no2%10;
if(rem1==rem2)
{
ans[i]=0;
i++;
}
else if(rem1!=rem2)
{
ans[i]=1;
i++;
}
no1=no1/10;
no2=no2/10;
}
for(i=i-1;i>=0;i–)
{
cout<<ans[i];
}
cout<<endl;
t–;
}
return 0;
}

Hi @soorya19k
You are getting wrong answer for test case in which no1 and no2 are greater than 10^9, because in that case no1 and no2 are out of range of hence it is showing wrong answer,. So to pass all the test cases just change int to long long.

Here is your corrected code :

If your doubt is clear then mark it as resolved.
