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 Fortran (gfortran v4.8.4) (judge verdict: Wrong Answer)

program prime_numbers
    implicit none
    integer(8) i, j,k, n,y
    
    integer(8) :: x(5) = (/3,5,7,11,13/)
    read (*,*)n
    y=0
    do i=3,5
                 
        if (x(i)*15<=n)then
         y=y+1
        end if

    end do
    write(*,*)y
    stop
end program prime_numbers
