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.Linq;

class Program
{
	static void Main()
	{
		var input = Console.ReadLine().Split();
		var a = int.Parse(input[0]);
		var b = int.Parse(input[1]);
		var c = int.Parse(input[2]);

		int count = 0;
		Enumerable.Range(a, b - a + 1).ToList().ForEach(x => { if (c % x == 0) count++; });
		Console.WriteLine(count);
	}
}
