### Prompt

Please formulate 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>
int main(){
	int a, b, c,x=0;
	std::cin >> a >> b >> c;
	for (int i=a;i<= b; ++i){
		if (c%i == 0){
			++x;
		}
	}
	std::cout << x<<"\n";
	return 0;
}
