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)

public partial class IntroductionToProgramming{
	public static void Main(){
		string[] line = System.Console.ReadLine().Split(' ');
		int a = int.Parse(line[0]);
		int b = int.Parse(line[1]);
		int c = int.Parse(line[2]);

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

		System.Console.WriteLine(counter.ToString());
	}
