### 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,sum=0;

cin>>a>>b>>c;
for(;a<=b;a++){
if(c%a==0)
sum++;



}
cout<<sum<<'\n';


return 0;
}
```
