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

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