Questions & Step-by-Step Solutions
In a doubly linked list, how many pointers does each node contain?
Step 1: Understand what a doubly linked list is. It is a type of data structure that consists of nodes.
Step 2: Know that each node in a doubly linked list has three main parts: data, a pointer to the next node, and a pointer to the previous node.
Step 3: Focus on the pointers. In a doubly linked list, each node has one pointer that points to the next node in the list.
Step 4: Also, each node has another pointer that points to the previous node in the list.
Step 5: Therefore, each node contains a total of two pointers: one for the next node and one for the previous node.
Doubly Linked List Structure – A doubly linked list is a data structure where each node contains pointers to both the next and previous nodes, allowing traversal in both directions.
