### Prompt

Generate 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>
using namespace std;
int main(){
int a,b,c;
int i,t;
t=0;
cin>>a>>b>>c;
for(i=1;i<=c;i++){
if(c%i==0 && a<=i && b>=i){
t++;
}
}
cout<<t<<endl;
}
```
