Chapter 20, Problem 4FTE
Explanation of Solution
Purpose of the given code:
The given code is used to remove the first node of a nonempty doubly linked list “myList”.
Given code:
/* Remove the first node of a nonempty doubly linked list "mylist" */
mylist = mylist.next;
Error in the given code:
User need to set the “prev” reference of “myList” to “null”. So, user needs to add below line to the given code:
/* If "myList" is not equal to "null", then */
if (myList.next != null)
/* Set the "prev" reference of "myList" to "null" */
myList...

Students have asked these similar questions
True or FalseA Circular Linked List has a special method called revolve() that shall move the tail reference to the previous node.
With Head node or not?
statement is: if(p->rlink != first) p = p->rlink;
O a. It is a Doubly linked list without Head node.
O b. It is a Doubly linked list with Head node.
The following method is defined within a linked list class. What does it do?
void MyList::doSomething() { Node* p = head;
while (p) { cout << p->value << " "; p = p->next; }}
Group of answer choices
inserts a node into linked list
deletes a node from linked list
displays contents of linked list
destroys the entire linked list

- When removing a node from a linked list, what are the two steps?arrow_forwardIt is a to the next node in the linked list, which is the property after it in the Node class.arrow_forwardC# Assume you have a LinkedList of Node objects. Both classes have all the normal operations shown below. Your job is to program the DeleteTail method of the LinkedList class. This method locates and deletes the last element of the linked list. You may not change its signature line. Keep your code clean, but no documentation is necessary. A good solution will be between 5 and 10 lines of code, not counting whitespace.arrow_forward

- 6. Suppose that we have defined a singly linked list class that contains a list of unique integers in ascending order. Create a method that merges the integers into a new list. Note the additional requirements listed below. Notes: ● . Neither this list nor other list should change. The input lists will contain id's in sorted order. However, they may contain duplicate values. For example, other list might contain id's . You should not create duplicate id's in the list. Important: this list may contain duplicate id's, and other list may also contain duplicate id's. You must ensure that the resulting list does not contain duplicates, even if the input lists do contain duplicates.arrow_forwardc++ Given main.py and a Node class in Node.py, complete the LinkedList class (a linked list of nodes) in LinkedList.py by writing the insert_in_ascending_order() method that inserts a new Node into the LinkedList in ascending order.arrow_forwardint F(node<int>&p){int c=0; while(p!=0){p=p->next; c++; } return c;} This function is a. return the number of items in the linked list b. return the number of items in a linked list and destroy the linked list c. None of these d. destroy the list and free all allocated nodesarrow_forward
- 3. void insert (Node newElement) or def insert(self, newElement) (4) Pre-condition: None. Post-condition: This method inserts newElement at the tail of the list. If an element with the same key as newElement already exists in the list, then it concludes the key already exists and does not insert the key.arrow_forwardWhen traversing a single- or double-linked list, you should be careful not to fall off the end of the list or you'll get a type your answer.arrow_forwardIn Java, a linked list always terminates with a node that is null.
