### 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,x,Ans;

scanf("%d %d %d",&a,&b,&c);
Ans=0;
for(x=a;x<=b;x++){

if(c%x==0){
Ans++;
}
}
printf("%d\n",Ans);

return 0;

}
