Types of Linked List
A sequence of data elements connected through links is called a linked list (LL). The elements of a linked list are nodes containing data and a reference to the next node in the list. In a linked list, the elements are stored in a non-contiguous manner and the linear order in maintained by means of a pointer associated with each node in the list which is used to point to the subsequent node in the list.
Linked List
When a set of items is organized sequentially, it is termed as list. Linked list is a list whose order is given by links from one item to the next. It contains a link to the structure containing the next item so we can say that it is a completely different way to represent a list. In linked list, each structure of the list is known as node and it consists of two fields (one for containing the item and other one is for containing the next item address).
Which node contains a pointer to its parent?
a) root node
b) right most child
c) left most child
d) left sibling
Step by step
Solved in 2 steps
- Empty list. Inserting a node with data 5 updates which pointers? Head and tail O TailTo insert node at the beginning of the list Select one: a. We need two pointers previous and follow b. Head is changed if it is NULL c. We need one pointer; temp that points to the created node d. We need 3 pointers previous, follow and temp that points to the created nodeThis function should delete the first node if RemoveID is at the first node and contains two pointers in which helps removes any node and reroute. What is wrong with the code? void remove(node *&first, int RemoveID) { node *prev = NULL; node *temp; temp = first; cout << "Enter ID that you want to delete" << endl; cin >> RemoveID; while (temp->ID != RemoveID) { prev = temp; temp = temp->next; if (first == NULL) { cout << "No lists" << endl; return; } else if (first->ID == RemoveID) { node *temp = first; first = first->next; delete temp; } } }

- True/False Select true or false for the statements below. Explain your answers if you like to receive partial credit. 3) Which of the following is true about the insertBeforeCurrent function for a CircularLinked List (CLL) like you did in programming exercise 1?a. If the CLL is empty, you need to create the new node, set it to current, andhave its next pointer refer to itselfb. The worst case performance of the function is O(n)c. If you insert a new element with the same data value as the current node, theperformance improves to O(log n)Department of Computer Engineering has student's club named 'Pinnacle Club'.
