Problem Statement

The number 105 is quite special - it is odd but still it has eight divisors.
Now, your task is this: how many odd numbers with exactly eight positive divisors are there between 1 and N (inclusive)?

Constraints

N is an integer between 1 and 200 (inclusive).

Input

Input is given from Standard Input in the following format:

N

Output

Print the count.

Sample Input 1

105

Sample Output 1

1

Among the numbers between 1 and 105, the only number that is odd and has exactly eight divisors is 105.

Sample Input 2

7

Sample Output 2

0

1 has one divisor. 3, 5 and 7 are all prime and have two divisors. Thus, there is no number that satisfies the condition.

Solution in C (GCC 5.4.1) (judge verdict: Accepted)

#include<stdio.h>

int main()
{
    int num,tem,res=0;
    scanf("%d",&num);
    for(int i=1;i<=num;i++)
    {
        tem=0;
        if(i%2==1)
        {

            for(int j=1;j<=i;j++)
            {
            if(i%j==0)
            {
                tem++;
            }
            }
            if(tem==8) res++;
        }
    }
    printf("%d\n",res);
    return 0;
}
