Linked Lists

Before starting: This article assumes a general understanding of javascript, and familiarity with the linked list data structure. If you are not familiar with linked lists the first half will still be easy to understand but I suggest looking at linked lists and a Javascript linked list implementation. This blog…

Hello everyone. Today, I am going to write about linked lists which are third topic of my data structure series. Are you excited as much as I am?? Then, Let’s start…..:) My dear reader, do you have any idea about what linked lists are and why they are used …

Different approaches to solve Leetcode 203 in JavaScript Linked lists are fundamental data structures widely used in programming and algorithmic problem-solving. One common task when working with linked lists is removing specific elements based on a given criterion. Problem Statement: Given the head of a linked list and an integer val, remove…

When working with sorted linked lists, a common challenge is removing duplicate nodes while preserving the original order of distinct elements. In this article, we will delve into solving the “Remove Duplicates from Sorted List” problem. …

If you guys study a linked list or work with a linked list, one common task is to find the middle node. In this article, we will explore different approaches to solve this question and implement their solutions in JavaScript. We will also analyze the time and space complexities of…

In this article, we will explore different approaches to check if the given linked list is a palindrome or not. Problem Statement: Given the head of a singly linked list, return true if it is a palindrome or false otherwise. Approach 1: Use Extra Array Traverse the linked list and copy each element into an array. Use…

What is a Linked List? A linked list consists of nodes where each node contains a data field and a reference(link) to the next node in the list. When can you use a linked list? The most common use case is the Histories of web browsers. The browser saves your visit history using a linked list structure when surfing various web. To…

Merging two sorted linked lists is a common problem in algorithmic coding interviews. The task is to merge the two lists into a single sorted list while maintaining the order of the elements. …

Reversing a linked list is a common problem asked in the interviews. It requires rearranging the pointers of each node to reverse the order of the list. In this article, we will explore the Iterative and Recursive approaches to solve this problem and their implementation in JavaScript. …
