#include<iostream>

using namespace std;

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

### Prompt

Please provide a cpp coded solution to the problem described below:

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