Question
In a doubly linked list, which pointer of a node points to the previous node?
next, prev, previous, back
Solution
In a doubly linked list, each node contains three main components: a data field, a pointer that points to the next node, and a pointer that points to the previous node. The pointer that points to the previous node is commonly referred to as the prev pointer. Therefore, the correct answer to your question is prev.
Doubly linked lists allow for traversal in both directions—forward and backward—thanks to these pointers, which is advantageous for various algorithms requiring flexibility in navigation. This makes doubly linked lists more versatile compared to singly linked lists, where each node has only a pointer to the next node.
