First one in, last one out
That's how you work a queue, yeah
Offer(), peek(), poll(), size(), and element() too
ArrayList, LinkedList
Gotta use these classes cause
Queue is just an interface and not a class itself

Gonna start an APT and it's gonna be a breeze
it's gonna be a breeze, yes it is
Gonna start an APT it'll take no time at all
But -- what I didn't expect was

I have to recurse for this
And oh my gosh, I'm the worst at this
Just last week we were working with queues
And now recursion's what I'll have to use

Time Limit Exceeded ?!?!
This is the last thing that I needed!
Infinite loops, what a curse
Recursion, you're the worst!

Oh no, oh no, oh no...

Red, red, red, I hit the keyboard til im numb
Tell ola I said hey, these apt-F¢s are really dumb-A
Mad pointers, bad pointers, that-F¢s just what they are, yeah-A
Makes me want to kick my computer really far

Gave it all my code and it tossed it in the trash
Garbage collector swept it up, yes, it did
To write a working code is all I ever asked
But what I didn't expect was

I have to recurse for this
And oh my gosh, I'm the worst at this
Just last week we were working with queues
And now recursion's what I'll have to use

Time Limit Exceeded ?!?!
This is the last thing that I needed!
Infinite loops, what a curse
Recursion, you're the worst!

If eclipse says there are errors
Oh, just watch me struggle with all of them
I'll click the test/run button in terror
---there's still red, red, red, red red red

But ola, I-F¢ll still do a green dance for ya-A
I'm gonna fix all the reds for ya
I-F¢d recurse all day long for ya-A
You know I-F¢d code anything for ya-A

No, I won't bubble sort anything
Cuz that sorting method's really lame
Maybe I'll just hard code these answers --
But is it the best way?

Oh, it depends
It all depends
yes, it depends
Yeahhh.
