In the last lesson, we learned about different types of trees, how they're constructed, and what they're used for. In this lesson, we'll learn two different methods for visiting the nodes in a tree.

With depth-first traversal, rather than visiting nodes level by level, we instead work our way down to the bottom of the tree first. Once we get to the bottom, we backtrack until we get to a node that ...
