public class MainClass {
public static void Main() {
long count = Enumerable.Range(0, int.MaxValue).
Concat(Enumerable.Range(0, int.MaxValue)).LongCount(n => n > 1 && n < 4); Console.WriteLine(count); } } [/csharp]

public class MainClass {
    public static void Main() {
        long count = Enumerable.Range(0, int.MaxValue).Concat(Enumerable.Range(0, int.MaxValue)).LongCount();

public class MainClass {
    public static void Main() {
        string[] presidents = {"G", "H", "a", "H", "over", "Jack"};

        string name = presidents.LastOrDefault(p => p.StartsWith("Z"));
        Console.WriteLine(name == null ? "NULL" : name);

    }
}

public class MainClass {
    public static void Main() {
        string[] presidents = {"G", "H", "a", "H", "over", "Jack"};
        string name = presidents.Take(0).LastOrDefault();
        Console.WriteLine(name == null ? "NULL" : name);
    }

public class MainClass{
   public static void Main(){
            int[] numbers = { 1, 3, 5, 7, 9 };
            var query = numbers.FirstOrDefault(n => n % 2 == 0);
            Console.WriteLine("The first even element in the sequence");
            Console.Write(query);
            Console.WriteLine("The last odd element in the sequence");
            query = numbers.LastOrDefault(n => n % 2 == 1);
            Console.Write(query);
   }
}
