An example of an AI chatbot conversation about inserting a node in a doubly linked list.
How do I insert a node in a doubly linked list?
To insert 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, create the new node. Then, adjust the pointers of the previous and next nodes to include the new node.
What if I want to insert it at the beginning?
If you're inserting at the beginning, set the new node's next pointer to the current head and update the head to the new node.
And how about inserting at the end?
For inserting at the end, traverse to the last node, set its next pointer to the new node, and set the new node's previous pointer to the last node.
