{
HashSet<int> evenNumbers = new HashSet<int>();
HashSet<int> oddNumbers = new HashSet<int>();
for (int i = 0; i < 5; i++)
{
evenNumbers.Add(i * 2);
oddNumbers.Add((i * 2) + 1);
}
HashSet<int> numbers = new HashSet<int>(evenNumbers);
numbers.UnionWith(oddNumbers);
foreach (int i in numbers)
{
Console.WriteLine(i);
}
}
}
