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;

class ITP1_3_D {
    public static void Main() {

        string[] Input = Console.ReadLine().Split(' ');

        int a = int.Parse(Input[0]);
        int b = int.Parse(Input[1]);
        int c = int.Parse(Input[2]);
        int count = 0;

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

        Console.WriteLine(count);
    }
}
