### Prompt

Create a solution in cpp for 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<bits/stdc++.h>
using namespace std;

 int main(){

 int a,b,c,x=0;
 cin>>a>>b>>c;
 for(int i=a;i<=b;i++){
 if(c%i==0) x=x+1;
}
cout<<x<<endl;

  return 0;
  }
