if(c%x == 0) i++;
}

cout<<i<<endl;

return 0;

}

### Prompt

Develop a solution in cpp 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<bits/stdc++.h>

using namespace std;

int main(){


int a,b,c,i;

cin>>a>>b>>c;

i=0;

for(int x=a;x<=b;x++){

if(c%x == 0) i++;
}

cout<<i<<endl;

return 0;

}
