### 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<bits/stdc++.h>
using namespace std;
int main(){
int a,b,c,d,e=0;
cin>>a>>b>>c;

for(a;a<b+1;a++){

d=c%a;

if(d==0){
e++;
}

}
cout <<e<<endl;
}
