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;


    public static class Program
    {
    static void Main()
    {

        var data1 = Console.ReadLine().Split(' ');
        var num = 0;
        int[] data3 = new int[3];
        for (var i = 0; i < 3; i++)
        {
            data3[i] = int.Parse(data1[i]);
        }
        for (var j = data3[0]; j <= data3[1]; j++)
        {
            if(data3[2] % j == 0)
            {
                num++;
            }
        }
        Console.WriteLine(num);
        
       
    }
    }
