#include <stdio.h>
int main(){

 int a,b,c,r=0;

 printf("%d\n",r);

 return 0;

}
### Prompt

Create a solution in Cpp for 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,r=0;

 scanf("%d %d %d",&a,&b,&c);

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

 printf("%d\n",r);

 return 0;

}
