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;

namespace noteCsharp
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] inputstr = Console.ReadLine().Split(char.Parse(" "));
            int c = int.Parse(inputstr[2]);
            int b = int.Parse(inputstr[1]);
            int result = 0;
            for(int a = int.Parse(inputstr[0]); a <= b; a++)
            {
                if (c % a == 0)
                {
                    result++;
                }
            }
            Console.WriteLine(result);
        }
    }
