### Prompt

Develop a solution in Cpp to the problem described below:

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>
int a,b,c;
int n=0;
int main(){
	std::cin>>a>>b>>c;
	for(int i=a;i<=b;++i){
		if(c%i==0)n+=1;
	}
	std::cout<<n<<std::endl;
	return 0;
}
