Binary tree traversal without recursion

WebIn this method, we have to use a new data structure-Threaded Binary Tree, and the strategy is as follows: Step 1: Initialize current as root Step 2: While current is not NULL, If current does not have left child a. Add current’s value b. Go to the right, i.e., current = current.right Else a. WebGiven the rootof a binary tree, return the inorder traversal of its nodes' values. Example 1: Input:root = [1,null,2,3] Output:[1,3,2] Example 2: Input:root = [] Output:[] Example 3: Input:root = [1] Output:[1] Constraints: The number of nodes in the tree is in the range [0, 100]. -100 <= Node.val <= 100
