I.2. Which statement is false?a) Linked lists are collections of data items "lined up in a row," insertions and deletions can be madeanywhere in a linked list.b) Insertions and deletions are made only at one end of a stack, its top. c) Insertions and deletions are made only at one end of a queue, its tail. d) Binary trees facilitate high-speed searching and sorting of data
Select true or false for the statements below. Explain your answers if you like to receive partial credit 8) Which of the following is true about the delete function in a standard linked list (only a head pointer and nodes only having a next pointer)?a. There is only 1 scenario to consider when looking for a node to delete in a linked listb. When you traverse the list to find the element to delete, it improves theperformance to O(1)c. You should always check first to see if the list is empty before attempting to find and delete a node
09.Given a linked list of N nodes such that it may contain a loop. A loop here means that the last node of the link list is connected to the node at position X(1-based index). If the link list does not have any loop, X=0. Remove the loop from the linked list, if it is present, i.e. unlink the last node which is forming the loop. Example 1: Input: N = 3 value[] = {1,3,4} X = 2 Output: 1 Explanation: The link list looks like 1 -> 3 -> 4 ^ | |____|
1) Which of the following statements are true about Linked Lists. a) Linked Lists use exactly as much memory as is needed for for all nodes. b) Linked Lists always have a head reference c) Linked Lists can grow dynamically d) None of these answers. e) Linked Lists are efficient when you need random access. 2) What is the average Big O runtime of retrieving a value of an item in a link list given its index? a) O(n) b) O(1) c) O(n^2) d) None of these answers. e) O(nlogn) 3) When does the insert() function of a Dynamic List have a big O runtime of O(1)? a) When you are inserting to the end of the list. b) When you are inserting to the beginning of the list. c) When the size of the data is small. d) None of these answers. 4) Why does retrieving a value from an array have a runtime of O(1)? (Select all that reasons that make this possible.) a) Arrays use simple math calculations to compute the requested index location. b) Arrays have to search…
True or False For each statement below, indicate whether you think it is True or False. provide a description of your answer for partial credit in case you are incorrect. 3) Given a priority queue implemented as a standard linked list with only a head pointer, insert performing at O(n) and remove at O(1), and the following functions performed (higher numbers represent higher priorities): Insert(“Rick”, 75), Insert(“Carol”, 80), Insert(“Daryl”, 65), Remove(), Insert(“Negan”, 60), Insert(“Maggie”, 25), Remove(), Insert(“Michonne”, 55) a. If Insert(“Eugene”, 40) is called, it will be added as the last node in the linked list b. The linked list from head to the end at this point is Rick, Negan, Michonne, and then Maggie c. Carol was the first element removed from the priority queue
Consider the following linked list: Give the correct sequence to steps to the list be like below: I Move pointer to position to insert i.e. node K II Point the new node to next of node K III Point the node K to the new node. IV Create new node S Select one: A.IV, I, II, III B.IV, I, III, II C.IV, III, II, I D.I, II, III, IV

Short answer Answer the following in your own words: 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 ended linked list). They said this significantly improved the performance for all functions (push, pop, search, and update). Are they correct? Why or why not? 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?
Consider the following linked list: Give the correct sequence to steps to the list be like below: I Move current pointer to the position to delete i.e. node D, II Move the previous pointer behind the current pointer i.e. node C III Make the node C to point to next of node D. IV Delete the node D Select one: A.II, I, IV, III B.I, II, III, IV C.IV, I, II, III D.IV, III, II, I
