#include<iostream>

}


### 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<iostream>
using namespace std;
int main(){
int a,b,c,z=0;
cin >> a >> b >> c;
for(int x=a; x<=b; x++){
if(c%x==0) z++;
}
cout << z <<endl;
return 0;
}
