### Prompt

Construct a Cpp code solution to the problem outlined:

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,d;
	cin>>a>>b>>c;
	d=0;
	for(a=a;a<=b;a++){
		if(c%a==0){
			d=d+1;
		}
		
	}
	cout<<d<<endl;
	return 0;
