Consider the following scenario: a software creates and manipulates a linked list, like follows:
The software would normally maintain track of two special nodes, which are as follows: Explanation of how to utilise the null reference in the node of the linked list in two frequent situations?
Step by step
Solved in 2 steps
- For example: Programming generates and modifies linked lists: Typically, the software monitors two nodes: How to utilise the null reference in the node of a linked list in two common scenarios.Computer Science Describe a situation where you may wish to create a link list of ITERATORS. Is it possible to create a link list of various types of iterators? For example a list with list iterators, map iterators, and set iterators?Think about the following example: A computer program builds and modifies a linked list like follows:Normally, the program would keep tabs on two unique nodes, which are as follows: An explanation of how to use the null reference in the linked list's node in two common circumstances
- Write the code to delete a node in the middle of a list implemented as a linked list with the dummy node (see Exercise 3). Compare your answer with the answer to Exercise 3. Are they the same? What do you conclude? Does the dummy node simplify the operation on the list? How?Consider the implementation of the Ordered Linked list class, implement the following functions as part of the class definition: ▪ index(item) returns the position of item in the list. It needs the item and returns the index. Assume the item is in the list. ▪ pop() removes and returns the last item in the list. It needs nothing and returns an item. Assume the list has at least one item. ▪ pop_pos(pos) removes and returns the item at position pos. It needs the position and returns the item. Assume the item is in the list. ▪ a function that counts the number of times an item occurs in the linked list ▪ a function that would delete the replicate items in the linked list (i.e. leave one occurrence only of each item in the linked list) Your main function should do the following: ▪ Generate 15 random integer numbers in the range from 1 to 5.▪ Insert each number (Item in a node) in the appropriate position in a linked list, so you will have a sorted linked list in ascending order.▪…Consider a Single Linked List (SLL) of nodes, where ‘node’ is a type with two fields: integer data and the node type reference ‘next’ that refers to the next node in the list. For each part given below consider the SLL and the code given in the second column. Following the execution of the code, show the resulting list (in the answer box, for each part, use the arrow key to draw the list as: head-----> ? -------> ? --------> ?). List and Java Code a head ⟶ 1⟶ 2⟶ 3⟶ 4⟶ null node ptr=head; node newnode = new node(0); // data=0 head = newnode; newnode.next=ptr; b head ⟶ 1⟶ 2⟶ 3⟶ 4⟶ null node ptr=head; node newnode = new node(6); // data=6 while(ptr.next!=null) { ptr=ptr.next; } ptr.next=newode; c head ⟶ 1⟶ 2⟶ 3⟶ 4⟶ null node ptr=head; ptr=ptr.next; head=ptr;
- I need a reference page for this question that was answered below. What is the difference between a singly-linked list and a doubly-linked list? In what situation would you use a singly-linked list over a doubly-linked list? In what situation would you use a doubly-linked list over a singly-linked list? If a node is in a linked list with N nodes, how many nodes will be traversed during a search for the node? Explain the best- and worst-case search scenarios. Explain why a singly-linked list defines a RemoveAfter() function, while a doubly-linked list defines a Remove() function. Could a RemoveAfter() function also be defined for a doubly-linked list? Explain why or why not. Could a Remove() function also be defined for a singly-linked list? Explain why or why not.Q4 Suppose, alist is a 2-dimensional list that is defined as follows. alist = [ [1], [2,3], [5,6,7] ] Which is the best option to access the last element of the last element of this list (i.e., 7)? Question 4 options: alist[ len(alist) - 1 ][len(alist[len(alist) - 1]) - 1] alist[ len(alist) - 1 ][len(alist[len(alist) - 1])] alist[3][3] alist[ len(alist) - 1 ][1]Given a scenario where you need to efficiently insert elements at the beginning of a list, which type of linked list would be most suitable? Explain why.
- in java, Two abstract data types are the ordered list and the unordered list. Explain how these two ADTs are similar and how they differ. To answer this question, assume that you do not know how they are implemented (that is, whether they are implemented using an array or a linked list).Consider the following example of a programme that builds and manipulates a linked list:What are the two specific nodes that the programme would typically monitor? Describe two common uses of the null reference in the linked list node.In a 2- to 3-page paper, you will build on the material given in the course to answer the following questions: What is the difference between a single and doubly linked list? When might a singly-linked list be preferable than a doubly-linked list? When might a doubly-linked list be preferable than a singly-linked list? How many nodes will be visited during a search for a node that is in a linked list with N nodes? Describe the best- and worst-case scenarios for a search. Explain why a singly-linked list has the RemoveAfter() function while a doubly-linked list has the Remove() function. Is it possible to create a RemoveAfter() method for a doubly-linked list as well? Explain why you think that is or why you don't think that is. Is it possible to create a Remove() method for a singly-linked list as well? Explain why you think that is or why you don't think that is. Format your work according to the APA standards for the course you're in.
