#include <iostream>

### Prompt

Your challenge is to write a CPP solution 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,f=0;
	cin>>a>>b>>c;
	for(int i = a;i<=b;++i){
		if(0==c%i){
			f++;
		}
	}
	cout<<f<<endl;
	return 0;
}
```
