### 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>
using namespace std

;

int main(){

int a, b, c, t, s;

cin>>a>>b>>c;

for(t=a, s=0;t<=b;t++){

if (c%t==0){

s++;

}

}

cout<<s<<"\n";

return 0;

}
