For tree, which of the following list traversing through the entire list is not necessary.
For a tree, circular list traversing through the entire list is not necessary. A circular liked list is a linked list where all nodes are connected to form a circle. There is no NULL at the end. A circular linked list can be a single circular linked list or doubly circular linked list.
Singly Linked Lists:- Singly Linked Lists are a type of data structure. In a singly linked list, each node in the list stores the contents and a pointer or reference to the next node in the list. It does not store any pointer or reference to the previous node.
Doubly linked list:- A doubly linked list is a linked data structure that consists of a set of sequentially linked records called nodes. Each node contains two fields, called links that are references to the previous and to the next node in the sequence of nodes.
