### Prompt

Develop a solution in cpp 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,num;
 num=0;
 cin>>a>>b>>c;
 for(int i=a;i<=b;i++){
  if(c%i==0){
   num++;
  }
 }
 cout<<num<<endl;
}
