In this tutorial, we will cover the preorder traversal ( DLR traversal ) in binary trees in both recursive and non-recursive methods. In preorder traversal, we process each node before either of its subtrees. Also, it is the simplest to understand binary tree traversal method….
A binary tree is a hierarchical data structure which has at most two child nodes, i.e no node in the tree can have a degree greater than two. For a binary tree, we distinguish between the subtree on the left and right as left subtree…
