### Prompt

Your challenge is to write 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>
int main(){
int x,y,d,j=0;
std::cin>>x>>y>>d;

for(int i=x;i<=y;i++){

if(d%i==0){
j=j+1;
}
}
std::cout<<j<<"\n";
return 0;
}
```
