#include<iostream>
int main(){
  int a,b,c,i,cnt;
  std::cin >> a >> b >> c;
  for(i=a,cnt=0; i<=b; i++) if(!(c % i)) cnt++;
  std::cout << cnt << std::endl;
  return 0;
}
### 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>
int main(){
  int a,b,c,i,cnt;
  std::cin >> a >> b >> c;
  for(i=a,cnt=0; i<=b; i++) if(!(c % i)) cnt++;
  std::cout << cnt << std::endl;
  return 0;
}
```
