I have submitted a program like Hello World for problem 136, but the runtime is 0.008.

Can anybody suggest some reason for the run time of 0.008 instead of 0.000?
my code is C++ like this:
#include<iostream>
using namespace std;
int main(void){
cout << "the answer\n";
return 0;
}

The problem states that "None of the input integers exceeds 3000",
so, array size of 2000 is not enough but 3000 is enough.
