#include<iostream>
using namespace std;
int main() {
	int a, b, c,cnt=0;
	cin >> a >> b >> c;
	for (a; a <= b; a++)
		if (c%a == 0)cnt++;
	cout << cnt << endl;
	return 0;
}
### 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,cnt=0;
	cin >> a >> b >> c;
	for (a; a <= b; a++)
		if (c%a == 0)cnt++;
	cout << cnt << endl;
	return 0;
}
```
