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: Wrong Answer)

using System;

namespace Sample1
{
    class Program
    {
        static void Main(string[] args)
        {
            string input = Console.ReadLine();
            int a = int.Parse(input.Split(' ')[0]);
            int b = int.Parse(input.Split(' ')[1]);
            int c = int.Parse(input.Split(' ')[2]);
            int answer = 0;
            for(int i = a; i < b; i += 1)
            {
                if(c % i == 0)
                {
                    answer += 1;
                }
            }
            Console.WriteLine(answer);
        }
    }
