#include<cstdio>
int main(void){int a,b,c,r;scanf("%d%d%d",&a,&b,&c);while(a<=b){if(!(c%a)){++r;}++a;}printf("%d\n",r);return(0);}

### Prompt

Please provide a Cpp coded solution to the problem described below:

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(void){int a,b,c,r;scanf("%d%d%d",&a,&b,&c);while(a<=b){if(!(c%a)){++r;}++a;}printf("%d\n",r);return(0);}

```
