### Prompt

Please formulate 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<cstdio>
int main(){
 int a,b,c,i=0;
 scanf("%d%d%d",&a,&b,&c);
 for(;a<=b;a++){
  if(!(c%a))i++;
 }
 printf("%d\n",i);
}
