Problem Description

There are many lamps in a line. All of them are off at first. A series of operations are carried out on these lamps. On the i-th operation, the lamps whose numbers are the multiple of i change the condition ( on to off and off to on ).

Input

Each test case contains only a number n ( 0< n<= 10^5) in a line.

Output

Output the condition of the n-th lamp after infinity operations ( 0 - off, 1 - on ).

Sample Input

1
5

Sample Output

1
0

Hint
hint
 

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.

代码：

#include <stdio.h>
int main()
{
    int n;
    int i;
    int count;
    while(~scanf("%d",&n))
    {
        count = 0;
        for(i=1;i<=n;i++)
        {
            if(n%i == 0)
                count++;
        }
        
        if(count%2==0)
            printf("0\n");
        else
            printf("1\n");
    }
    return 0;
}
