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.

import java.util.Scanner;

public class Main {
	
	static Scanner sc = new Scanner(System.in);
	
	public static void main(String[] args) {
		int n = sc.nextInt();
		
		int ans = 0;
		for(int i = 1; i <= n; i+=2) {
			int sum = 0;
			for(int j = 1; j <= i; j++) {
				if(n % j == 0) sum++;
			}
			if(sum == 8) ans++;
		}
		
		System.out.println(ans);
	}
