#include<iostream>
using namespace std;
int main(void){
  int a,b,c,t;

  return 0;
}


### 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(void){
  int a,b,c,t;
  cin>>a>>b>>c;
  for(int i=a;i<=b;i++){
    if(c%i==0)t++;
  }
  cout<<t<<endl;
  return 0;
}
