#include<iostream>

### Prompt

Your challenge is to write 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,k=0;
	std::cin >>a>>b>>c;
	
	for (int i=a; i<=b; i++){
		
		if (c%i==0)k++; 
		
	}
	
	std::cout <<k <<"\n";
	
	return 0;
	
}
```
