#include

using namespace std;

int count_of_divisors(int n)
{
    int res = 0;

    for (int i = 2; i * i <= n; ++i)<br>        if (n % i == 0)
            res += 2 - (i *i == n);

    return res + 2 - (n == 1);
}

int main()
{
    int n;
    cin >> n;
    cout << count_of_divisors(n) << endl;<br>}
//Ассимптотика O(log(n));
