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;
using System.Collections.Generic;

class Program {
    static int Main(string[] args) {
        string v = Console.ReadLine();
        
        int a = int.Parse(v.Split(' ')[0]);
        int b = int.Parse(v.Split(' ')[1]);
        int c = int.Parse(v.Split(' ')[2]);

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

        Console.WriteLine(cnt);

        return 0;
    }
}
