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 PHP (5.6.30) (judge verdict: Runtime Error)

<?php
  fscanf(STDIN, "%d", $a);
  $count = 0;
  $totalCount = 0;

  if($a < 105){
    echo 0;
    break;
  }

  for($i = 105; $i < $a; $i++){
    for($j = 0; $j < $i; $j++) {
      if($i % $j == 0) {
        $count++;
      }
    }
    if($count == 8){
      $totalCount++;
    }
    $count = 0;
  }
