Singly Linked Lists vs. Doubly Linked Lists

Explore the key differences between singly and doubly linked lists in this lesson. Understand how doubly linked lists enable bi-directional traversal and more efficient deletion, and learn how adding a tail pointer can optimize insertion and deletion operations, providing practical insights into linked list performance in C++.

Which is Better? #

DLLs have a few advantages over SLLs, but these perks do not come without a cost:

  • Doubly linked lists can be traversed in both directions, which makes them more compatible with complex algorithms.
  • Nodes in doubly linked lists require extra memory
