#include<bits/stdc++.h>
using namespace std;
int main(){int a, b, c, div=0; cin>>a>>b>>c; for(int i=a; i<=b; i++){if(c%i==0){div++;}}cout<<div<<endl;}

### Prompt

Create a solution in CPP for 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, div=0; cin>>a>>b>>c; for(int i=a; i<=b; i++){if(c%i==0){div++;}}cout<<div<<endl;}

```
