42: Collections: Left-Child Right-Sibling Tree.

A game that only has one character with one quest and with one shop that sells one item is not going to be very fun. That is why you need to be able to work with collections of items. You have choices and this episode continues more than a week long exploration of collection types available. Up today is the left-child right-sibling tree. I will explain what these trees are and then give you some guidance on when to use them.
