Deletion in doubly link list
WebI will stick with this - Doubly LinkedLists cannot have O (1) for deleting any node. You still need to start either from head or tail, which brings it down to O (n). " If " we have the pointer to the node to be deleted say X, then of course it's O (1) because we have pointers to the next and prev node we can delete X. WebSteps to delete from end in doubly linked list in C++ Following steps are involved in deletion of last node from a doubly linked list :- 1.) Traverse till the last node 2.) Change the next of last second node with null. 3.) Delete the last node Defining doubly linked list in C++ struct Node { int Data; Struct Node* next ; Struct Node* prev ; };
