Welcome to Day 20 of my 100 Days of DSA challenge! Today, I solved five problems focused on basics of binary trees. Here's a quick look at the questions I tackled and how I approached them 🤖✨ Check out my GitHub repository for all my solutions and p...
Introduction Binary Search Trees (BSTs) are a specialized form of binary trees designed to optimize the searching process. While a standard binary tree offers no inherent structure to facilitate faster lookups, BSTs introduce a pivotal property: for...
In computer science, trees are a fundamental non-linear data structure composed of nodes connected by edges. A tree is a hierarchical model that represents a collection of elements, each of which can have a number of children but only one parent (exc...
Introduction A Binary Search Tree (BST) is a data structure that maintains sorted data in a way that allows for efficient insertion, deletion, and lookup operations. Each node in a BST has the following properties: Node: Contains a value (data). Le...
Binary search trees (BSTs) are a fundamental data structure commonly used in computer science, offering several advantages over traditional and linked lists. Unlike linear structures, BSTs provide logarithmic time complexity for critical operations, ...
class Solution { public boolean isValid(TreeNode root, long minLimit, long maxLimit){ if(root == null) return true; if(root.val <= minLimit || root.val >= maxLimit) return false; return (isValid(root.left, minLimit, root....
Introduction : Binary Search Trees (BSTs) are foundational data structures in the realm of computer science, celebrated for their efficient search, insertion, and deletion operations. Their elegant design leverages a hierarchical arrangement of nodes...
Welcome back to my blog, dear readers! Today, I'm stepping into the realm of Java and diving into Binary Search Trees (BSTs). Whether you're a seasoned Java developer or someone just getting started, I hope you'll find this exploration both informati...
