### Prompt

In cpp, your task is to solve 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;
int cnt=0;
cin >> a >> b >> c;
for(int i=a;i<=b;i++)
{
if(c%i==0) cnt++;
}
cout << cnt << endl;
return 0;
}
