#include <iostream>

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

Please provide a CPP coded solution 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 <iostream>

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