the challenge is in how getting the input and handling int size..otherwise it is just a simple substraction

Solution :
#include
using namespace std;
int main(){
//freopen(“10055I.txt”,”r”,stdin);
//freopen(“10055IO.txt”,”w”,stdout);
long long x,y,z;
while(cin>>x>>y){
if(x>y){
cout<} else {
cout<}
}
}
