What is the time complexity of deleting an element from a doubly linked list?

Step 1: Understand what a doubly linked list is. It is a data structure where each node has a reference to both the next node and the previous node.
Step 2: Know that to delete a node, you need to have a pointer (or reference) to that specific node.
Step 3: When you have the pointer to the node to be deleted, you can access its previous and next nodes directly.
Step 4: Update the previous node's next pointer to point to the next node of the node being deleted.
Step 5: Update the next node's previous pointer to point to the previous node of the node being deleted.
Step 6: Finally, you can remove the node from memory (if needed).
Step 7: Since all these operations (updating pointers) take a constant amount of time, the time complexity for deleting a node is O(1).
