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 ConsoleApp4
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] str = Console.ReadLine().Split(' ');
            int one = int.Parse(str[0]);
            int two = int.Parse(str[1]);
            int three = int.Parse(str[2]);
            int count = 0;
            for (int i = one; i <= two; i++)
            {
                if (three % i == 0)
                {
                    count++;
                }

            }
            Console.WriteLine(count);


        }
    }
