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: Runtime Error)

const yakusuu = (N) => {
    let count = 0
    for(let i = 0; i <= N; i++) {
        if(N % i === 0) {
            count++;
        }
    }
    return count
}

const Main = (input) => {
    const N = Number(input)
    let count = 0;
    for(let i = 0; i <= N; i++) {
        if(i % 2 === 0) {
            continue;
        }
        if(yakusuu(i) === 8) {
            count++;
        }
    }
    console.log(count)
}
