### Prompt

Construct a CPP code solution to the problem outlined:

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,n=0;
	cin >> x >> y >> z;
	while(x<=y){
		if(z%x==0){
			n++;
		}
		x++;
	}
	cout<<n<<"\n";
	return 0;
}
