Doubly Linked Lists
Understand how doubly linked lists operate with nodes containing references to both previous and next nodes. Learn to implement and traverse doubly linked lists in C#, enabling efficient forward and backward navigation useful for applications like browser history and undo-redo functions.
At this stage, singly linked lists and operations such as insertion, deletion, and traversal have been covered. In a singly linked list, each node stores a value and a reference to the next node. This design supports traversal in the forward direction, one node at a time.
However, singly linked lists have an important limitation. Since each node only stores a link to the next node, traversal is only possible in one direction. If we are currently at a node and want to return to the previous node, there is no direct way to do ...
