We can maintain one pointer last and get the first (head) node using the next pointer of the last node. I know that the Java LinkedList API is quite extensive. a bad implementation using linked list where you enqueue at head and dequeue at tail would be O(n) because you'd need the next to last element, causing a full traversal each dequeue; enqueue: O(1) (amortized, linked list and array [probing]) dequeue: O(1) (linked list and array) empty: O(1) (linked list and array) Hash table. Purpose. . 40 the present record points to its next record and the next one points to the record that comes after it, this goes on until the end of the structure) a) Each node has only one pointer to traverse the list back and forth b) The list has breakpoints for faster traversal c) An auxiliary singly linked list acts as a helper list to traverse through the doubly linked list d) A doubly linked list that uses bitwise AND operator for storing addresses Structure of singly linked list in Java.
