#include <iostream>
using namespace std;

int main()
{
	int a, b, c, n = 0;

	cin >> a >> b >> c;

	for (; a <= b; a++)
		if (c % a == 0)
			n++;

	cout << n << endl;
}

### 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>
using namespace std;

int main()
{
	int a, b, c, n = 0;

	cin >> a >> b >> c;

	for (; a <= b; a++)
		if (c % a == 0)
			n++;

	cout << n << endl;
}
