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