Among the integers between A and B (inclusive), it is either within the K smallest integers or within the K largest integers.

Constraints

1 \leq A \leq B \leq 10^9

1 \leq K \leq 100

All values in input are integers.

Input

Input is given from Standard Input in the following format:

A B K

Output

Solution in C# (Mono 4.6.2.0) (judge verdict: Accepted)

using System;
using System.Linq;

class Program
{
	static void Main(string[] args)
	{
		var numbers = Array.ConvertAll(Console.ReadLine().Split(new[] { ' ' }), number => int.Parse(number));
		var min = numbers[0];
		var max = numbers[1];
		var range = numbers[2];

		var results = Enumerable.Range(min, range).Where(number => number <= max).ToList();
		results.AddRange(Enumerable.Range(max - range + 1, range).Where(number => number >= min));
		results = results.Distinct().ToList();
		results.Sort();

		results.ForEach(number => Console.WriteLine(number));
	}
