public class MainClass{
public static void Main(String[] argv){
HashSet<int> lowNumbers = new HashSet<int>();
HashSet<int> allNumbers = new HashSet<int>();
for (int i = 1; i < 5; i++)
{
lowNumbers.Add(i);
}
for (int i = 0; i < 10; i++)
{
allNumbers.Add(i);
}
Console.WriteLine(lowNumbers.Overlaps(allNumbers));
}
