WebApr 5, 2024 · Threaded Binary Tree Advantages: A linear traversal of the items in this Tree is possible. Since it does a linear traversal instead of using a stack, memory is conserved. Allows for the automatic use of the parent pointer without explicitly doing so. The nodes of a threaded tree can be traversed both forward and backward in an orderly method. WebAmong them are the inorder, preorder and postorder traversal of nodes. Each of these traversal algorithms visit every node of the BST in a particular order. InOrderTraversal : The idea of inorder traversal is that we visit the nodes in the order left-root-right, meaning for any subtree in the path, left node must be visited first followed by root and right node.

WebAug 23, 2024 · Given a binary tree, return the inorder traversal of its nodes’ values. Example: Input: [1,null,2,3] 1 \ 2 / 3 Output: [1,3,2] (you can solve this problem here).
