#include <iostream>

int main(){
    int a, b, c, count=0;
    std::cin >> a >> b >> c;
    for(; a <= b; a++) if(c%a==0) count++;
    std::cout << count << std::endl;
}

### 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>

int main(){
    int a, b, c, count=0;
    std::cin >> a >> b >> c;
    for(; a <= b; a++) if(c%a==0) count++;
    std::cout << count << std::endl;
}
