#include <iostream>

using namespace std;

int a,b,c,i,x;

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

### Prompt

Your challenge is to write a CPP solution 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 a,b,c,i,x;

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

```
