How do I delete a node in a doubly linked list?

To delete a node in a doubly linked list, you need to adjust the pointers of the surrounding nodes.

Can you explain the steps in detail?

Sure! First, locate the node you want to delete. Then, update the previous node's next pointer to the node's next pointer, and the next node's previous pointer to the node's previous pointer.

What if the node is the head or the tail?

If it's the head, update the head pointer to the next node. If it's the tail, update the tail pointer to the previous node.

Are there any edge cases I should consider?

Yes, consider cases where the list is empty or has only one node, as well as ensuring you handle null pointers.
