Linked Lists

A linked list is a way to organize and store data where each item, called a node, contains the data and a reference (or link) to the next node in the sequence. Think of it like a chain of paperclips, each connected to the next. This structure allows efficient insertion and deletion of elements without shifting other items, unlike a traditional array. Linked lists are flexible, scalable, and useful when the size of the data set changes frequently. They are fundamental in computer science and underpin many complex data structures and algorithms.
