Problem Description Given a linked list, remove nth node from end of list and return its head. The list can have various sizes, and the node we need to remove can be anywhere from the beginning to the end of the list. Approach To solve this problem efficiently, we need to think about how to … Read more
Introduction Queues are an essential data structure in computer science, and they can be implemented in various ways. In this guide, we will focus on how to implement a queue using a linked list in Java. By the end of this article, you’ll understand the fundamentals of a queue, how linked lists work, and how … Read more
Introduction When dealing with data structures in Java, linked lists are a powerful tool, providing efficient ways to manage and organize data. While most programmers are familiar with singly and doubly linked lists, the circular linked list is an equally important variation that has unique characteristics and applications. In this comprehensive guide, we’ll explore circular … Read more
Introduction A doubly linked list is an extension of the singly linked list, with added flexibility due to its two-way links between nodes. In a doubly linked list, each node points to both its next and previous nodes, enabling bidirectional traversal. This feature makes operations like insertion, deletion, and traversal faster in certain scenarios compared … Read more
Introduction: Singly Linked Lists are fundamental data structures widely used in programming and problem-solving. Unlike arrays, linked lists do not have a fixed size, allowing for dynamic data management. In this blog post, we’ll explore the concept of a singly linked list, its applications, and walk through a step-by-step Java implementation. To learn more about … Read more
The LeetCode Problem 2: Add Two Numbers is a classic linked list problem, and it’s a common interview question for testing algorithmic and coding skills. This problem can be solved in multiple ways, starting from a brute force approach to more optimized solutions. In this article, we’ll walk through various solutions, starting from the most … Read more
When working with data structures, we often come across various types that allow us to store and manage data efficiently. Among them, linked lists hold a special place due to their dynamic nature, making them incredibly useful in scenarios where memory allocation is unpredictable. In this blog, we will cover everything you need to know … Read more
