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: Accepted)

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

    }
  }
  if($count==8){
   $array[]=$i;
  }
}
$count2=0;
for ($l=0; $l <count($array) ; $l++) {
  // code...
  if($array[$l]%2==1){
    $count2++;
  }
}
echo $count2;
 ?>
