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 program
{
    public static void Main()
    {
        int i = 0, a, b, c;
        
        string[] x = Console.ReadLine().Split(' ');
        a = int.Parse(x[0]);
        b = int.Parse(x[1]);
        c = int.Parse(x[2]);
        while (a <= b)
        {
            if (c % a == 0)
            {
                i++;
               
            }
            a++; 
        }
        Console.WriteLine(i);
    }
}
