### 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 <stdio.h>
int main()
{
int a, b, c;
scanf("%d %d %d", &a, &b, &c);
int t = 0;
for(int i = a; i<=b; ++i)
{
if( 0 == c%i)
++t;
}
printf("%d\n",t);
return 0;
}
```
