Question
Chapter 21.2, Problem 6E
Program Plan Intro
To modify the UNION procedure for the linked-list representation that removes the need to keep the tail pointer to the last object in each list. The running time of the procedure should not change.

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?

- In this question, you are to implement two functions for reversing linked lists. One function, reverse_iter(..), must use an iterative approach (i.e., loops), whereas the other function, reverse_rec(..), must use recursion instead.

A link-based implementation does not need to shift entries over to make room when adding a new entry to the List c.

Explain why.arrow_forwardImportant: Make all your implementation in the same attached file and submit only one file in the submission link. Given the linked list data structure discussed in the lecture, implement a sub-class TSortedList that makes sure that elements are inserted and maintained in an ascending order in the list. So, given the input sequence {1,7,3,11,5}, when printing the list after inserting the last element it should print like 1, 3, 5, 7, 11. Note that with inheritance, you have to only care about the insertion situation as deletion should still be handled by the parent class. In the basic implementation, assume that you only have head which is a pointer to the head of the list. Now, if we have both head and tail pointers, what improvements can be done to speed up the insertion?arrow_forward
