Binary Tree Inorder Traversal Problem Statement: Given the root of a binary tree, implement a function to return an array containing the inorder traversal of its nodes' values. Input Specification: The input is given as a binary tree represented by level order traversal with 1 indicating null nodes. The first element is the root. Output Specification: Return an array/list of integers representing the inorder traversal. Constraints: The number of nodes in the tree is in the range [0, 10^4]. 1000 <= Node.val <= 1000 Examples:
