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.

<?php
fscanf(STDIN,'%d',$N);
for ($i=1; $i <=$N ; $i+=2) {
  // code...
  $yaku=0;
  $count=0;
  for ($m=1; $m <=$i ; $m++) {
    // code...
    if ($i%$m==0) {
      // code...
      $yaku++;
    }


  }
  if ($yaku==8) {
    // code...
    $count++;
  }
}
echo $count;

 ?>
