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;

namespace Project
{
	class MainClass
	{
		public static void Main(string[] args)
		{
			string s = Console.ReadLine();
			string[] sar = s.Split(' ');
			int a, b, c;
			a = int.Parse(sar[0]);
			b = int.Parse(sar[1]);
			c = int.Parse(sar[2]);
			int number = 0;
			for (int i = a; i <= b; i++)
			{
				if (c % i == 0) { number++; }
			}
			Console.WriteLine(number);
		}
	}
