Binary Tree Inorder Traversal

Hi Geeks! In this article, we going to look at the Binary Tree in Inorder Traversal. 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] Follow up: Recursive solution is trivial, could you do it iteratively? Solution – Recursive approach But in our given problem, …
