### Prompt

Please create a solution in Cpp 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 x,y,z,ans=0;
  cin>>x>>y>>z;
  for(int i=x;i<=y;i++){
    if(z%i==0) ans++;
  }
  cout<<ans<<"\n";
}
