Adding Reversed Numbers

[arpitmehta5]

it shows wrong answer while in my local machine it shows the right output.

#include
using namespace std;
int main()
{
int t,m,n,rem=0;
cin>>t;

for(int i=0;i<t;i++)
{
int revnum1=0,revnum2=0,revnum3=0,sum=0;
    cin>>m;
    cin>>n;
    while(m!=0)
            {
                rem=m%10;
                revnum1=revnum1*10+rem;
                m=m/10;
            }
    while(n!=0)
            {
                rem=n%10;
                revnum2=revnum2*10+rem;
                n=n/10;
            }
    sum=revnum1+revnum2;
    while(sum!=0)
            {
                rem=sum%10;
                revnum3=revnum3*10+rem;
                sum=sum/10;
            }
            cout<<revnum3;


}
return 0;

}

Test it with the example input given in the problem. Does the output match the example output exactly?
