### Prompt

Construct a Cpp code solution to the problem outlined:

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 <bits/stdc++.h>
using namespace std;
int main(){
int a,b,c,ans=0;
cin>>a>>b>>c;
for(int i=a;i<=b;i++){
  if(!(c%i))ans++;
}
cout<<ans<<endl;
  return 0;
}
