import java.lang.*;
import java.util.Scanner;
public class Main{
public static void main(String args[]){
Scanner sc= new Scanner(System.in);
System.out.println("enter the number of customers");
int numOfCusomers=sc.nextInt();
List<String> customersList = new ArrayList<String>(); //list
while(numOfCusomers!=0)
{
customersList.add(sc.nextLine());
numOfCusomers--;
}
  
System.out.println("Printing List: "+customersList);
PriorityQueue<String> pq = new PriorityQueue<>(); // priority queue
pq.add("z"); //
pq.add("y");
pq.add("x");
System.out.println("PriorityQueue: " + pq);
}
}
