#include <iostream>
using namespace std;
int main(){
  
int a,b,c;
cin >> a >> b >>c;
int count=0;
for(int i=a;i<=b;i++){
  if(c%i==0)count++;
}
cout << count << endl;
}
### Prompt

Please formulate 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 a,b,c;
cin >> a >> b >>c;
int count=0;
for(int i=a;i<=b;i++){
  if(c%i==0)count++;
}
cout << count << endl;
}
```
