How to Find the Minimum Distance Between Nodes in a Binary Search Tree (BST) – Optimized Solution Explained
In a Binary Search Tree (BST), finding the minimum absolute difference between the values of any two distinct nodes is a classic problem in tree data structure algorithms. This problem is a natural extension of the concept of BST properties and is useful in scenarios such as range queries, nearest neighbor searches, and optimization problems. In this blog post, we’ll walk through the approach to solve the problem of finding the minimum distance between two nodes in a BST. We will break down the solution, discuss different strategies, and demonstrate an optimized approach to solve the problem efficiently. Problem Statement: Minimum Distance Between BST Nodes (LeetCode Problem 783) Problem Description: You are given the root of a Binary Search Tree (BST). Your task is to find the minimum absolute difference between the values of any two distinct nodes in the tree. For example: Input 1: root = [4, 2, 6, 1, 3] Output: 1 The nodes with values 2 and 3 have the smallest absolute difference
