WebDepth first traversal using recursion: pre- and post-order The first two traversals that we consider are called “depth first”. There are two ways to do depth-first-traversal of a tree, depending on whether you visit a node before its descendents or after its descendents. In a pre-order traversal, you visit a node, and then visit all its ...
