Tree Traversal

Tree traversal is a method for visiting all the nodes in a tree data structure systematically. Think of it like exploring a family tree: you can choose different paths—such as visiting the parent node first, then children, or children first. Common methods include in-order (left, root, right), pre-order (root, left, right), and post-order (left, right, root). These methods help organize, search, or process the data stored in a tree efficiently, making sure every node is visited in a specific order suited to the task at hand.
