### 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>
	using namespace std;

	int main(){
		int a,b,c,i=0;
		cin>>a>>b>>c;
		for(int x=a;x<=b;x++){
			if(c%x==0) i++;
		}
		cout<<i<<endl;
	}
