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 JavaScript (node.js v5.12) (judge verdict: Accepted)

function main(input) {
  var answer = 0;

  for (var i = 1; i <= input; i++) {
    var counter = 0;
    for (var j = 1; j <= i; j++) {
      if(i % 2 == 0){
        continue;
      }
      if(i % j == 0) {
        counter++;
      }
    }
    if (counter == 8) {
      answer++;
    }
  }

  console.log(answer);
}
main(require('fs').readFileSync('/dev/stdin', 'utf8'));
