Linked List Visualization


OVERVIEW

A Linked List is a linear data structure consisting of nodes, where each node contains a value and a reference to the next node in the sequence. Unlike arrays, linked lists provide dynamic memory allocation and efficient insertions and deletions.

Operations

  • Insertion: Adds a new node at the beginning, end, or a specific position in the linked list.
  • Deletion: Removes a node from the beginning, end, or a specific position in the linked list.
  • Traversal: Accesses each node sequentially to process the data stored in the linked list.
  • Search: Finds a node containing a specific value in the linked list.
  • Update: Modifies the data of a specific node in the linked list.

Terminologies

  • Node: A fundamental unit of a linked list containing data and a reference (or pointer) to the next node.
  • Head: The first node in a linked list. It serves as the starting point for traversal.
  • Tail: The last node in a linked list, which usually points to NULL (in singly linked lists).
  • Pointer: A reference to another node in the linked list, helping in navigation.
  • Linked List Types: Includes singly linked list, doubly linked list, and circular linked list.
