Questions & Step-by-Step Solutions
In what scenario would you use a doubly linked list?
Step 1: Understand what a doubly linked list is. It is a data structure where each element (node) has a reference to both the next and the previous node.
Step 2: Identify the need for bidirectional traversal. If you want to move forward and backward through the list easily, a doubly linked list is useful.
Step 3: Consider scenarios where you need to insert or delete nodes from both ends of the list. A doubly linked list allows for efficient operations at both ends.
Step 4: Think about applications like browser history, where you need to go back and forth between pages. A doubly linked list can help manage this efficiently.
Step 5: Conclude that a doubly linked list is best when you need flexibility in navigating the list in both directions.
