Question: 1 / 400

What is the purpose of the 'Next' property in a doubly linked list node?

To point to the previous node

To point to the first node

To point to the next node

In a doubly linked list, each node contains two references that allow traversal in both directions: forward and backward. The 'Next' property specifically serves to point to the next node in the sequence. This is essential for maintaining the structure of the list, as it enables the algorithm to access the subsequent node easily during operations such as insertion, deletion, or traversal.

By having the 'Next' property, any node can connect to the one that follows it, thereby allowing the entire list to be navigated in a linear fashion from the head node to the end of the list. This facilitates efficient operations that rely on the ordered nature of the list, enhancing both the performance and flexibility of the data structure. Each node also has a 'Previous' property to point back to the preceding node, allowing for bidirectional navigation, which is a key feature of doubly linked lists.
