Why Use Singly Linked List?

Singly linked list is preferred when we need to save memory and searching is not required as pointer of single index is stored. ... As singly linked list store pointer of only one node so consumes lesser memory. On other hand Doubly linked list uses more memory per node(two pointers).

What are the pros and cons of using a singly linked vs doubly linked list?

Doubly-linked lists can be used in places where singly-linked lists would not work (a doubly-ended queue), but they require slightly more "housekeeping", and are slightly less efficient on insertions as the result. Advantage of single linked list: Less housework to be done on update/insert/delete, less memory usage.

Why is doubly linked list more useful than singly linked list?

Following are advantages/disadvantages of doubly linked list over singly linked list. 1) A DLL can be traversed in both forward and backward direction. 2) The delete operation in DLL is more efficient if pointer to the node to be deleted is given. 3) We can quickly insert a new node before a given node.
