Master Linked Lists

Introduction to Linked Lists and Basic Operations

• Linked lists are collections of nodes connected through links, with each node containing data and a pointer to the next node in the list.
• Unlike arrays, linked lists have no defined size limit, allowing for flexible storage and deletion of data.
• There are three types of linked lists: singly linked lists, doubly linked lists, and circular linked lists.
• Singly linked lists have one link between nodes, enabling traversal in one direction only, while doubly linked lists have two links allowing for traversal in both directions.
• Circular linked lists can be either singly or doubly linked and have a last node that connects back to the first node.
• Basic operations in linked lists include insertion, deletion, searching, display, and deleting an element at a given key.
• Insertion involves creating a new node and linking it to the appropriate location in the list, which can be done at the beginning, end, or any position within the list.
• Deletion involves locating the target node and removing its link, then deallocating or keeping the node in memory.
• Reverse operation involves making the last node point to the head node and reversing the entire list.
• Search operation involves comparing each element in the list with a given key element to find a match.
• Traversal operation involves walking through all the elements of the list in order and displaying them.
• Linked lists can be implemented in various programming languages, such as C, C++, Java, and Python.
