⁉️What is Linked List?
Double linked list is a data structure in which each node has two
pointers, one pointing to the previous node and another to the next
node. This allows for bidirectional traversal of the list, making it
easier to access and manipulate data.
👍Advantages of Linked Lists:
- Bidirectional traversal allows for more efficient searching, sorting, and manipulation of data.
- Insertion and deletion operations can be performed without needing to iterate through the entire list.
- The list can be traversed in both forward and backward directions.
👎Disadvantages of Linked Lists:
- Double linked lists use more memory than singly linked lists because each node has two pointers instead of one.
- There is an additional overhead cost in maintaining the two pointers for each node.
📌Use Cases:
- Implementing data structures such as stacks and queues that require efficient insertion and deletion of elements.
- Implementing undo/redo functionality in applications such as text editors.
- Building caching mechanisms for frequently accessed data.
🖊️Summary:
A double linked list is a variation of the linked list data structure that allows for bidirectional traversal of the list. It has advantages such as efficient searching, sorting, and manipulation of data, as well as the ability to traverse the list in both forward and backward directions.
However, it uses more memory and has an overhead cost in maintaining the two pointers for each node. It is useful in a variety of applications such as implementing data structures, undo/redo functionality, and caching mechanisms.
