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