#include<iostream>
using namespace std;

 	int a,b,c,dem=0;
 	cin>>a>>b>>c;
 	for(int i = a;i<=b;i++){
 		if(c%i==0) dem++;
	 }

 }

### 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<iostream>
using namespace std;
 int main(){
 	int a,b,c,dem=0;
 	cin>>a>>b>>c;
 	for(int i = a;i<=b;i++){
 		if(c%i==0) dem++;
	 }
	cout<<dem<<endl;
 }
