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 Scala (2.11.7) (judge verdict: Wrong Answer)

import java.util.Scanner

object Main {
  def main(args: Array[String]): Unit = {
    val sc: Scanner = new Scanner(System.in)
    val number: Int = sc.nextLine.toInt
    if (number < 105) println(0)
    else if (number == 105) println(1)
    else {
      println((105 until number).map {
        n =>
          (1 to Math.sqrt(number).toInt).foldLeft(0) {
            case (acc, d) if n % d == 0 => acc + 1
            case (acc, _) => acc
          }
      }.count(_ == 8))
    }

  }
