In this problem, we solve LeetCode Problem 94: Binary Tree Inorder Traversal.
You are given the root of a binary tree and need to return the inorder traversal of its node values.
Key idea:
✔ Inorder traversal follows the order Left → Root → Right
✔ Use recursion to visit nodes in the correct sequence
✔ Collect values in a list and return it
This is one of the most basic and important binary tree problems, commonly asked in coding interviews and essential for understanding tree traversals.
