WebFor traversing a (non-empty) binary tree in a preorder fashion, we must do these three things for every node n starting from the tree’s root: (N) Process n itself. (L) Recursively traverse its left subtree. When this step is finished, we are back at n again. (R) Recursively traverse its right subtree.
