Singly Linked Lists vs. Doubly Linked Lists
Explore the core differences between singly and doubly linked lists, focusing on traversal capabilities, deletion operations, and memory trade-offs. Understand how doubly linked lists enable efficient tail deletions and bidirectional traversal, and compare their time complexities and memory requirements. This lesson helps you grasp practical implementation details crucial for coding interviews.

Which is Better? #
DLLs has a few advantages over SLLs
- Doubly linked lists can be traversed in both directions, which makes them more compatible with complex algorithms.
- Operations involving tail become much faster. Deletion at the tail is one such example.
These benefits entail the cost of extra memory:
- Nodes in doubly linked lists require extra memory to store the
previousElementpointer.
