Integer numNumbers is read from input, representing the number of integers that will be read from input. A for loop iterates numNumbers times using loop variable i$.$ In each iteration:

Read an integer from input.

If i is even, add the integer read to the head of ticketNumbers.

import java.util.LinkedList;

import java.util.Deque;

import java.util.Scanner;

public class TicketNumbers $\{$

public static void main$($String$[]$ args$)\{$

Scanner scnr $=$ new Scanner$($System$.$in$)$;

Deque ticketNumbers;

int numNumbers;

int i;

ticketNumbers $=$ new LinkedList$()$;

numNumbers $=$ scnr$.$nextInt$()$;

for $($i $=0$; i $<$ numNumbers; $++$i$)\{$

$\}$

$//$ Prints each element of the deque from the head

for $($i $=0$; i $<$ numNumbers; $++$i$)\{$

System.out.print$($ticketNumbers$.$removeFirst$()+"")$;

$\}$

System.out.println$()$;

$\}$

$\}$

Otherwise, add the integer read to the tail of ticketNumbers.

Ex: If the input is:

$6758514016216884$

then the output is:

$168140758516284$
