Consider the second test case:

The initial condition	   : 0 0 0 0 0 …
After the first operation  : 1 1 1 1 1 …
After the second operation : 1 0 1 0 1 …
After the third operation  : 1 0 0 0 1 …
After the fourth operation : 1 0 0 1 1 …
After the fifth operation  : 1 0 0 1 0 …

The later operations cannot change the condition of the fifth lamp any more. So the answer is 0.

#include <iostream>
using namespace std;

int main()
{
	int n;
	while (cin >> n)
	{
		int num=0; 
		for (int i=1; i<=n; i++)
		{
			if (n %i ==0)
				num++;
		}
		if (num%2 == 0)
			cout << 0;
		else
			cout << 1;
		cout <<endl;
	}
	return 0;
