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