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). WebFeb 18, 2024 · For the Binary Search Tree (BST), Inorder traversal gives the sorted array of values. Post-Order Traversal In this traversal, we will traverse the leftmost subtree first, then the rightmost subtree after the root. All the traversals will be in Post-Order. Let’s demonstrate an example: Here for root = 1, We’ll go to the left subtree first.
