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

Solution in C# (judge verdict: Accepted)

using System;

 class Program
 {
     static void Main(string[] args)
     {
         double data0, data1, data2;
         double[] result = new double[3];
         String nyuryoku;
         nyuryoku = Console.ReadLine();
         string[] data = nyuryoku.Split(' ');
         data0 = Double.Parse(data[0]);
         data1 = Double.Parse(data[1]);
         data2 = Double.Parse(data[2]);
         double count = 0;
         for (double i = data0; i <= data1; i++)
         {
             if((data2%i)==0)
                 count++;
         }
         Console.WriteLine(count);


      }
