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 C++14 (GCC 5.4.1) (judge verdict: Wrong Answer)

#include <iostream>
using namespace std;

int main(void) {

	int n;
	int ans = 0;
	int count = 0;
	cin >> n;

	for (int i = 1; i <= n; i++) {
		count = 0;
		//奇数の時
		if (i % 2 == 1) {
			for (int j = 1; j <= i; j++) {
				//約数
				if (n % j == 0) {
					count++;
				}
				
			}
			
		}
		if (count == 8) {
			ans++;
		}
	}
	
	cout << ans;

}
