import java.util.LinkedList;
import java.util.Queue;
import java.util.Scanner;

public class Test {
    public static void main(String[] args) {

        Scanner s = new Scanner(System.in);
        Queue<String> waitingQueue = new LinkedList<>();
        int num;
        System.out.print("Enter number of player: ");
        num = s.nextInt();

        do
        {
            System.out.print("Enter player name: ");
            String name = s.nextLine();
            waitingQueue.add(name);
            num--;
        }while(num > 0);

        System.out.println("WaitingQueue : " + waitingQueue);

        String name = waitingQueue.remove();
        System.out.println("Removed from WaitingQueue : " + name + " | New WaitingQueue : " + waitingQueue);

        name = waitingQueue.poll();
        System.out.println("Removed from WaitingQueue : " + name + " | New WaitingQueue : " + waitingQueue);
    }
}
