 Tree traversal

The summary from www.geeksforgeeks.org/tree-traversals-inorder-preorder-and-postorder/ is a winner:

In principle one could talk about tree traversal of unordered trees as a number of possible traversals without a fixed order. But we won't consider that under this section, only deterministic ordered tree traversals.

Tree traversal is the process of visiting each node in a tree data structure in a specific order. It is a fundamental operation used in various tree algorithms, including searching, sorting, and data processing. There are several methods to perform tree traversal, each with its own order of visiting nodes.
