- For a list L, L[i] = item operation is a ____ operation, if i is less then len(L). Question 8 options: O(n) O(exp(n)) O(log(n)) O(1)True/False Select true or false for the statements below. Explain your answers if you like to receive partial credit. 3) Which of the following is true about the insertBeforeCurrent function for a CircularLinked List (CLL) like you did in programming exercise 1?a. If the CLL is empty, you need to create the new node, set it to current, andhave its next pointer refer to itselfb. The worst case performance of the function is O(n)c. If you insert a new element with the same data value as the current node, theperformance improves to O(log n)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
- We learnt this week that lists can be multi-dimensional. For e.g., the following is another example of 2-D multidimensional list. Each row contains student name followed by their grades in 5 subjects: students = [ ['Anna', 98.5, 77.5, 89, 93.5, 85.5], ['Bob', 77, 66.5, 54, 90, 85.5], ['Sam', 98, 97, 89.5, 92.5, 96.5] ] To access, a specific row, you would use students[row_number][column_number]. students[0][0] would print 'Anna' students[0][1] would print 98.5 and so on.. Write a program that defines a function that takes a list as an argument, adds the scores of each student, calculate average for each student (append them to a separate list) and display them. Your program should: Define a function display_average(students) that takes in a 2-D list as an argument. Display the original list using for/while loop. Calculate and display the average of each student. You do not need to ask user for input. You can use your own 2-D lists with at-least 2-rows.Implement a program using Doubly LinkedList. Your doubly linked list should store information of students (Reg_no., Name, CGPA, city, age). Your program should provide following functionalities: Insert at Front Insert at Rear Insert in middle Delete from front Delete from rear Delete from middle Display all the data Data Structures in C++ Needed urgent i will thumb up for youHi! I am doing this function but it isn't working. how can I fix it def bubble_down(values: list, left: int, right: int) -> None: """Bubble down through values[left: right+1], swapping items that are out of order. Note that use of this slicing notation means that items values[left], values[left + 1], values[left + 2], ..., values[right] could be modified. Precondition: left and right are valid indexes in values. >>> list_example_1 = [4, 3, 2, 1, 0] >>> bubble_down(list_example_1, 1, 3) >>> list_example_1 [4, 1, 3, 2, 0] >>> list_example_2 = [4, 3, 2, 1, 0] >>> bubble_down(list_example_2, 0, 4) >>> list_example_2 [0, 4, 3, 2, 1] """ for i in range(left, right): if values[i] > values[i + 1]: values[i], values[i + 1] = values[i + 1], values[i]
- Create a doubly link list with at least 5 nodes, then perform the following operation on that link list. As you perform the operation, write down the algorithm and c++ code too. Show the operations diagrammatically. Traversal Searching SortingUse the standard linked list below to answer True/False statements 9-12: 9) The “head” pointer of this list is pointing to Node 4 10) If we called “insert(5)”, the new node’s “next” pointer will point to Node 8 11) If we called “delete(10)”, Node 7’s “next” pointer will point to Node 8 12) If we called “search(20)”, the “head” pointer will be at Node 4 after the search function endsIf a list L has not yet reached its maximum capacity, the L.insert(i, item) action is considered a operation.
- Which of the following structures would be the most efficient to use if you wanted to establish a priority queue for quick retrieval? Choose one: a. a doubly linked list that is sorted O b. array of ordered elements a. unordered singly linked list b. unordered singly linked list c. unordered singly linked O d. an unsorted arraySelect 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 nodewrite a function that add any item in a linked list after the item X, if the item X is not found in the linked list don't add the item. data structre please solve it fast less than 30 minute
