}
### Prompt

Please provide a Cpp coded solution 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 main(){
	int a,b,c,i,num=0;
    std::cin >> a >> b >> c;
	for(;a<=b;a++){
	i=c%a;
	if(i==0)num++;
	}
    std::cout << num <<std::endl;
	return 0;
}
