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
 $N = fgets(STDIN);
$result = 0;
$yakusu = 0;
for($i = 1;$i <= 200;$i++){
     if($N%$i === 0){
         $yakusu = $yakusu + 1;
     }
}
if($yakusu == 8){
echo 1;
}else{
echo 0; 
}
