How do I debug a doubly linked list in my code?
An example of an AI chatbot conversation about debugging doubly linked lists.
How do I debug a doubly linked list in my code?
Debugging a doubly linked list involves checking pointers and ensuring they point to the correct nodes. What issues are you facing?
I think my nodes are not linking correctly. Some nodes seem to be lost.
That could happen if the next or previous pointers are not set correctly. Can you share your code snippet?
Sure, here it is: Node* newNode = new Node(data); newNode->next = current; current->prev = newNode; But it seems like the previous pointer is not updating.
It looks like you might be missing the update for the previous pointer of the next node. Make sure to set current->next->prev = newNode; after linking.
Oh, I see! That makes sense. I'll try that. Thanks!
