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;

namespace HelloWorld
{
    class Program
    {
        static void Main()
        {
            string alpha = Console.ReadLine();
            string[] beta = alpha.Split(' ');
            int x = int.Parse(beta[0]);
            int y = int.Parse(beta[1]);
            int c = int.Parse(beta[2]);
            int count = 0;
            for (int a = x; a <= y; a++)
            {
                if (c % a == 0) count++;
            }
            Console.WriteLine(count);
        }

    }
