Welcome to LeetCode LevelUp!
In today’s video, we solve LeetCode Problem 94: Binary Tree Inorder Traversal using Java. This problem is a core interview question that helps evaluate your understanding of tree traversal and stack data structures. We’ll implement an iterative inorder traversal with a stack, which is optimal for space in this problem.
We’ll cover:
The problem statement and key ideas for approaching binary tree traversal iteratively.
A whiteboard walkthrough explaining how the stack manages node traversal.
Detailed Java code implementation to perform inorder traversal and capture node values in a list.
Important edge cases like empty trees and single-node trees.
Complexity Analysis:
Time Complexity: O(n), where n is the number of nodes in the tree, as each node is visited once.
Space Complexity: O(h), where h is the height of the tree, due to the stack’s depth for storing nodes.
This is a space-efficient and optimal iterative solution for inorder traversal.
