✅ Binary Search Tree to Greater Sum Tree - LeetCode 1038 - Reverse Inorder Traversal - Explained
Показать описание
Welcome to our channel! In today's video, we'll be solving a fascinating problem: converting a Binary Search Tree (BST) into a Greater Tree. We'll start by understanding the problem statement and then dive into the intuition and approach behind the solution. By using a reverse in-order traversal, we can efficiently update each node to become the sum of all nodes greater than it in the BST.
Here's what we'll cover:
Problem Explanation: Detailed breakdown of the problem with an example.
Intuition: Understanding the logic behind the approach.
Step-by-Step Solution: Visualizing the solution using tables and step-by-step updates.
Code Implementation: Writing the code in Java, C++, Python, and JavaScript.
Complexity Analysis: Analyzing the time and space complexity of our solution.
By the end of this video, you'll have a thorough understanding of how to tackle this problem efficiently. Whether you're preparing for coding interviews or enhancing your problem-solving skills, this video is for you!
