Thanks for the video! Just wondering why we are using a LinkedList as the output as opposed to an ArrayList? Is there any benefit or just an arbitrary choice?

Great content! You are helping me understand. I am now a subscriber. I like how you explained preorder, in order, and post order. If I had to give any recommendations it would be to slow down your delivery by about 10% - 15%. Also maybe make your diagrams larger. Great content tho!
