WebDec 28, 2010 · In-order, Pre-order, and Post-order traversals are Depth-First traversals. For a Graph, the complexity of a Depth First Traversal is O (n + m), where n is the number of nodes, and m is the number of edges. Since a Binary Tree is also a Graph, the same applies here. The complexity of each of these Depth-first traversals is O (n+m). WebSep 8, 2024 · I made a program that takes user input to create a binary tree, with options to traverse said tree based on user input. Inserting and Preorder traversal work fine, but for some reason Inorder traversal prints the same output as Preorder, and Postorder traversal prints the input backwards.
