You would still need to traverse the list to find which node has that particular p1 and then update that node. That p1 does not help you to get access to those prev/next members. When you create LinkedList ll, there is a private node class involved that contains a reference to a Person, but has in addition those prev/next references. That will not work like you hoped, because Person does not have the prev/next properties. Suppose I have a LinkedList ll, I have the Person p1 and I want to do ll.remove(p1). It is only fair to include that work in the work of deleting the k th node. So that means if you want to delete the k th node in the list, you'll have to traverse the list to locate it first. So you never have a reference to the element to delete.Įven if you use an alternative implementation where you do have access to the nodes, you start out with a reference to the head node only, not with an array of references to all nodes in the list. The API only provides access to the values in the linked list, not the nodes. Java's LinkedList class implements a doubly linked list, but its nodes are private. Printf("\n1.Push\n2.Pop\n3.Show\n4.If you already have the element, then indeed the delete operation has a time complexity of O(1). Printf("\n\nChose one from the below options.\n") The next node of the head node now becomes the head node.
