1) Your friend says they implemented a stack as a linked list with reference pointers to both a head and the tail node (i.e. they implemented a stack as a double endedlinked list). They said this significantly improved the performance for all functions (push, pop, search, and update). Are they correct? Why or why not?

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.
Short answer Answer the following in your own words: 1) Another friend implemented a queue as a linked list with only a head pointer (no tail node). She said this made performance of all functions (insert, remove, search, and update) categorically equal to a queue as a linked list with a head and a tail node. Is she correct? Why or why not?
During our conversation about Stacks, Queues, and Deques, we talked about the circular array implementation of a queue. 1. Why didn't we need a circular array implementation of a stack? What quality, specifically, does a queue have that led to a need for the circular array implementation? (You need to be specific here, but shouldn't require more than a sentence of two to answer this.) 2. You've seen that the dynamically-allocated array underlying a std::vector is resized periodically. Propose an algorithm for resizing the array used in the circular array implementation of a queue when it comes time to enqueue an element and the array is full. How much larger is your new array? How do the contents of your queue look different than before? 3. Assuming your algorithm was used to solve the problem of resizing the array when it's full, what is the amortized running time of the enqueue operation? (You may want to refer back to the Amortized Analysis lecture while you consider this.)
Is it possible to implement a sorted linked list using a DLL? What is the advantage of using a DLL versus a single linked list? Back up your point with a real example or application.
Please help with this. I really needed help.
Programming language: Java Topic: linked list
Question 42 What makes implementing a queue with a Doubly Linked List relatively easier than implementing a queue with a typical array, where all elements stay in adjacent locations? There's no need to explicitly shift the elements of a Linked List to the front, as there would be in an array. There's no need to keep track of how many elements are present, as there would be in an array. There is no advantage to using a Linked List implementation over an array implementation. There's no need to keep track of a front and a back, as there would be in an array.
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?
Java Programming language Please help me with this. Thanks in advance.
Refer to screenshot below. What would the code block do?
1. Give an example of the memory representation of a single linked list. 2. Linked lists outperform arrays in various ways. Mention some benefits.
The specifications for the Sorted List ADT state that the item to bedeleted is in the list.1. Rewrite the specification for DeleteItem so that the listis unchanged if the item to be deleted is not in the list.2. Implement DeleteItem as specified in (a) using anarray-based implementation.3. Implement DeleteItem as specified in (a) using alinked implementation.4. Rewrite the specification for DeleteItem so that allcopies of the item to be deleted are removed if they exist.5. Implement DeleteItem as specified in (d) using anarray-based implementation.6. Implement DeleteItem as specified in (d) using alinked implementation.
