### Prompt

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