#include <iostream>

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