}
### Prompt

Your task is to create 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 main(){

  int num,i,en,count=0;
  cin>>i>>en>>num;

  for(i; i<=en; i++)if(num%i==0)count++;

  cout<<count<<"\n";

}
```
