Doubly Linked List Explained

A doubly linked list is a linear data structure where each node has a data part and two pointers: one to the next node and another to the previous node.

Algorithm Characteristics

  • Time Complexity (Insertion)O(1)
  • Time Complexity (Deletion)O(1)
  • Space ComplexityO(n)
  • Memory UsageMore than singly linked list
  • DirectionBidirectional

Key Properties

  • Each node has pointers to both the next and previous nodes.

  • Allows traversal in both directions.

  • Efficient for applications requiring backward navigation.

  • Requires more memory compared to singly linked lists.

Doubly Linked Lists are used when backward traversal is needed.
