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

Solution in C# (judge verdict: Accepted)

using System;
using System.Collections.Generic;

class Program
{
    static void Main(string[] args)
    {
        var str = Console.ReadLine();
        string[] strer = str.Split(' ');
        var list = new List<int>();
        int count = 0;

        foreach (var s in strer)
        {
            list.Add(int.Parse(s));
        }

        for (int i = list[0]; i <= list[1]; i++)
        {
            if((list[2] % i) == 0)
            {
                count++;
            }
        }

        Console.WriteLine(count);
        
    }
}
