using System.Linq;
using System.Text;

public class MainClass {
    public static void Main() {
        int[] numbers = { 5, 4, 1, 3, 9};

        var lowNums =
            from n in numbers
            where n < 5
            select n;

        Console.WriteLine("Numbers < 5:");
        foreach (var x in lowNums) {
            Console.WriteLine(x);
        }
