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
{
    static void Main()
    {
            int a, b, c, count = 0,i ;
            string inp = Console.ReadLine();
            string[] data = inp.Split(' ');
            a = int.Parse(data[0]);
            b = int.Parse(data[1]);
            c = int.Parse(data[2]);
            for (i = a; i <= b; i++)
            {
                if (c % i == 0)
                {
                    count++;
                }
            }
            Console.WriteLine("{0}", count);
    }
}
