#include <iostream>
int main(){
int a,b,c,i=0;
std::cin>>a>>b>>c;
for(;a<=b;a++)!(c%a)?i++:0;
std::cout<<i<<std::endl;
return 0;
}
### Prompt

Please create a solution in CPP 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 <iostream>
int main(){
int a,b,c,i=0;
std::cin>>a>>b>>c;
for(;a<=b;a++)!(c%a)?i++:0;
std::cout<<i<<std::endl;
return 0;
}
