Linked List
A linked list is a linear data structure where elements, called nodes, are stored in non-contiguous memory locations and linked together using pointers or references. Each node contains data and a reference to the next node, allowing dynamic memory allocation and efficient insertions/deletions compared to arrays. It is fundamental in computer science for implementing other data structures like stacks, queues, and graphs.
Developers should learn linked lists to understand core data structure principles, optimize memory usage in applications requiring frequent insertions or deletions (e.g., real-time systems or dynamic lists), and prepare for technical interviews where algorithmic efficiency is tested. It is essential for low-level programming, such as in operating systems or embedded systems, where memory management is critical.
