I've submitted such code and got Time Limit Exceeded (on test 1):

#include <cstdio>
using namespace std;
typedef long long ll;
int main() {
    ll x, y;
    scanf("%lld%lld", &x, &y);
    if(x > 22147483647LL || y > 22147483647LL) while(1);
    return 0;
}

but in the statement of the task there are constrains X <= Y <= 2^31-1.
please, verify your input files.
