}


### 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>
using namespace std;

int main() {
	int a,b,c,i,x;
	cin >>a>>b>>c;
	for (i=a, x=0; i<=b; i++) {
		if (c%i==0) {
			x=x+1;
		}
	}
	cout <<x<<endl;
}
