Linked lists are one of the fundamental data structures in software development. Examples of linked lists can be found in many, if not all, applications. Although, as a developer you may never have to explicitly code a linked list.
It is still important to know what a linked list is, how to write a linked list, and why they are used. In addition, as a software engineer, being able to identify problems where linked lists can be applied is essential.
