Linked list is a dynamic data structure so it can grow and shrink at runtime by allocating and deallocating memeory. So there is no need to give initial size of linked list. Insertion and Deletion. Insertion and deletion of nodes are really easier. In computer science, tree traversal (also known as tree search) is a form of graph traversal and refers to the process of visiting (checking and/or updating) each node in a tree data structure, exactly once.Such traversals are classified by the order in which the nodes are visited.
