#include <iostream>
using namespace std;

int main(){
    int a=0, b=0, d=0, c=0;
    cin >> a >> b >> d;
    for(; a<=b; ++a) if(d%a==0) ++c;
    cout << c << endl;
}

### Prompt

Please create a solution in Cpp to the following problem:

How Many Divisors?

Write a program which reads three integers a, b and c, and prints the number of divisors of c between a and b.

Constraints

* 1 ≤ a, b, c ≤ 10000
* a ≤ b

Input

Three integers a, b and c are given in a line separated by a single space.

Output

Print the number of divisors in a line.

Example

Input

5 14 80


Output

3

### Response

```cpp
#include <iostream>
using namespace std;

int main(){
    int a=0, b=0, d=0, c=0;
    cin >> a >> b >> d;
    for(; a<=b; ++a) if(d%a==0) ++c;
    cout << c << endl;
}
