![]() Usual approach for query would be traverse. All operations (push(), pop(), and peekMin()) are O(1) not O(n). It’s one concept that I try to remain mindful of when working with linked lists. This stack class can return its minimum element. Because linked lists are a simple data structure, it is easy to lose track of edges and break connections when I didn’t intend to. ![]() After a bit of practice and understanding of the fundamentals, I have found that linked lists can be more useful than an array and offer me much better performances during runtime of certain functions and operations. Problem Statement (link): Merge k sorted linked lists and return it as one. Sometimes, I struggle with understanding how linked lists work and how to implement it within some of my projects or coding challenges. LeetCode Meeting Rooms II (Java) Given an array of meeting time intervals. Most often, the code for a node looks like the following: public class Node Conclusion To break it down even further, a Node is a data structure that contains the value of the node and reference/pointer to the next node. What is a Linked List?Ī linked list is a series of nodes that are connected to one another. I kind of got stumped on that coding challenge this week and thought that if I drew some diagrams, I may help others visualize how reversing a linked list should work. This past week, the only topic that inspired me to write was having to reverse a linked list. ![]() One of the other challenges that I face is finding topics to write about for my blog. Over the past few weeks, I have been focusing my attention on solving code challenges on and reviewing my skills with JavaScript on. I am starting to assume that the challenges that I face with getting a response to my applications for different software development roles have to do with my lack of experience in the industry and the struggles that I have with code challenges. ![]()
