### Prompt

In Cpp, your task is to solve 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;
	int t=0;
	
	cin>>a>>b>>c;

	for(int i=0 ; i<b-a+1 ;i++){
		if(c%(a+i)==0)
			t++;
	}
	cout<<t<<"\n";
}
```
