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 Kotlin (1.0.0) (judge verdict: Accepted)

fun main(args:Array<String>):Unit {
  val sc = java.util.Scanner(System.`in`)
  val n = sc.nextInt()
  println((1..n).filter { it % 2 == 1 }.filter { v ->
    (1..v).asSequence().filter { v % it == 0 }.count() == 8
  }.count())
}
