Singly Linked Lists vs. Doubly Linked Lists
Understand key differences between singly and doubly linked lists, including traversal directions, memory requirements, and deletion efficiency. Learn how adding a tail pointer optimizes insertion and deletion operations in both types, enhancing data structure performance for coding interviews.

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 to
