Which of the given variation of the linked list can be used when concatenation of two lists can be performed in O(1) time?OptionsDoubly linked listSingly linked listCircular doubly linked listArray implementation of list

Which of the following operations is performed more efficiently by a doubly linked list than by a linearly linked list?

Consider an implementation of unsorted singly linked list. Suppose it has its representation with a head pointer only. Given the representation, which of the following operation can be implemented in O(1) time?i) Insertion at the front of the linked listii) Insertion at the end of the linked listiii) Deletion of the front node of the linked listiv) Deletion of the last node of the linked listOptionsI, II and IVI and III and IIII, II and III

What is a memory efficient double linked list?Select one:a.Each node has only one pointer to traverse the list back and forthb.The list has breakpoints for faster traversalc.An auxiliary singly linked list acts as a helper list to traverse through the doubly linked listd.A doubly linked list that uses bitwise AND operator for storing addresses

Which of the following is true for a doubly linked list compared to a singly linked list?It consumes less memory.It allows traversal in both forward and backward directions.It does not use pointers.It has faster insertion and deletion at the end.

How is a doubly linked list different from a singly linked list in terms of memory usage?Doubly linked list uses less memory.Doubly linked list uses more memory.Both use the same amount of memory.Memory usage depends on the size of the list.
