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: Wrong Answer)

function main(input) {
  var N = input[0]-0;
  var ans = 0;
  for(var i=105;i<=N;i++){
    var cnt = 0;
    for(var j=1;j<=i;j++){
      if(i%j==0) cnt++;
      if(cnt>8) break;
    }
    if(cnt == 8) ans++;
  }
  console.log(ans);
}
main(require('fs').readFileSync('/dev/stdin', 'utf8').trim().split("\n"))
