#include <iostream>
using namespace std;

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

### Prompt

In cpp, your task is to solve 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,b,c,m=0;
  cin >> a >> b >> c;
  for(int i=a;i<=b;i++){
    if(c%i==0)
      m++;
  }
  cout << m << endl;
}
