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 PHP7 (7.0.15) (judge verdict: Wrong Answer)

<?php
  
  fscanf(STDIN,"%d",$N);

$count=0;
$tmp_div = 0;
$result = 0;

for($i=1;$i<= $N;$i++){
  $tmp_div = $i;
  if($i%2==1){
    
    
    echo $tmp_div."\n";
    
  	for($j=1;$j<=$i;$j++){
    if($i%$j == 0){
      	$count++;
      }
  	}
  }
  if($count==8){
    $result++;
  }
  $count=0;



}

echo $result."\n";
