![]() ![]() It's something that helped me understand it much better. Here's a trick when creating a Linked List. The most important thing is to understand how it works. We'll do this using Python, but most of what we learn here applies to any language you are using. Now with all the theory out of the way, it's time to implement one. These are a few things you should consider before trying to implement a linked list. You need constant time insertion/deletion from the list (unlike an array, you don't have to shift every other item in the list first).You want to be able to insert items in the middle of the list.You don't need random access to any elements (unlike an array, you cannot access an element at a particular index in a linked list).You don't know how many items will be in the list (that is one of the advantages - ease of adding items).You should use a linked list over an array when: Unlike an array, you don't have the option of random access. Search operations on a linked list are very slow.This is because you need a pointer (which takes up its own memory) to point you to the next element. More memory is required when compared to an array.Linked lists also don't require a fixed size or initial size due to their chainlike structure.Linear data structures are often easier to implement using linked lists. This also doesn't require reorganizing the data structure unlike arrays or lists. Because of the chain-like system of linked lists, you can add and remove elements quickly.Like every other data structure, linked lists have their pros and cons: Advantages of Linked Lists: You can think of it as an actual chain, where each ring or node is connected. Each element in a linked list is called a node. The structure of a linked list is such that each piece of data has a connection to the next one (and sometimes the previous data as well). Linked Lists are a data structure that store data in the form of a chain. Another data structure commonly used is called a Linked List. These all do an awesome job storing and accessing data, but sometimes you might need something different. Some of the data structures you can use are collections such as arrays, lists, maps, sets, and so on. Different programming languages offer different ways to store and access data. ![]()
