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.

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.

Constraints

1 ≤ a, b, c ≤ 10000

a ≤ b

Sample Input 1

5 14 80

Sample Output 1

3

Solution in C# (judge verdict: Accepted)

using System;

class test{
    static void Main(){
        string[] str;
        str=Console.ReadLine().Split(' ');
        int a=int.Parse(str[0]);
        int b=int.Parse(str[1]);
        int c=int.Parse(str[2]);
        int n=0;
        for(;a<=b;a++){
            if(c%a==0)n++;
        }
        Console.WriteLine(n);
    }
}
