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;
using System.Collections.Generic;

class MainClass
{
    public static void Main(string[] args)
    {
        string[] str=Console.ReadLine().Split(' ');

        int a=Convert.ToInt32(str[0]);
        int b=Convert.ToInt32(str[1]);
        int c=Convert.ToInt32(str[2]);
        int count=0;

        for(int i=a;i<=b;i++)
        {
            if(c%i==0) count++;
        }

        Console.WriteLine(count);
    }
}
