Transcript from the "Tree Traversal" Lesson
>> Bianca Gandolfo: We're gonna traverse through our tree, which requires us to understand how to loop through or traverse a data structure like a tree. Let's jump to that, here are our leaves. Let's just talk about traversing. There are different traversal techniques and it all has to do about which order we visit a node.
