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 ConsoleApplication13
{
    class Program
    {
        static void Main(string[] args)
        {
            int n=0;
            String[] s = Console.ReadLine().Split(' ');
            int a = int.Parse(s[0]);
            int b = int.Parse(s[1]);
            int c = int.Parse(s[2]);

            while (true)
            {
                if (c % a == 0)
                {
                    n++;
                }
                if (a == b) break;
                a++;
            }

            Console.WriteLine(n);
        }
    }
