3) Which of the following is true about the insertBeforeCurrent function for a Circular
Linked List (CLL) like you did in
a. If the CLL is empty, you need to create the new node, set it to current, and
have its next pointer refer to itself
b. 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, the
performance improves to O(log n)

- You are given the pointer to the head node of a linked list and an integer to add to the list. Create a new node with the given integer. Insert this node at the tail of the linked list and return the head node of the linked list formed after inserting this new node. The given head pointer may be null, meaning that the initial list is empty. Function Description Complete the insertNodeAtTail function in the editor below. insertNodeAtTail has the following parameters: SinglyLinkedListNode pointer head: a reference to the head of a list int data: the data value for the node to insert Returns SinglyLinkedListNode pointer: reference to the head of the modified linked list Input Format The first line contains an integer , the number of elements in the linked list.The next lines contain an integer each, the value that needs to be inserted at tail. Constraints Sample Input STDIN Function ----- -------- 5 size of linked list n = 5 141 linked list data values…in C++ kth ElementExtend the class linkedListType by adding the following operations:a. Write a function that returns the info of the kth element of the linked list. If no such element exists, terminate the program.b. Write a function that deletes the kth element of the linked list. If no such element exists, terminate the program. Provide the definitions of these functions in the class linkedListType. please, do not copy from any other sources, give me a fresh new code. Thank youcomplete the following function. // It is the same as observeCounter except that f has a parameter of type List[Counter] not Counter. // f will insist that the List[Counter] has length 3. // You must return a List[Int] not an Int. // The first element of the result List[Int] must correspond to the number of times that increment/decrement were called on the first element of type List[Counter], similarly for the second and third elements. def observeCounterList (f : List[Counter] => Unit) : List[Int] = { // TODO: Provide definition here. List (-1, -1, -1) }
- Which of the following statements regarding linked lists and arrays is correct? Group of answer choices: a. A dynamically resizable array makes insertions at the beginning of an array very efficient. b. Using a doubly linked list is more efficient than an array when accessing the ith element of a structure. c. A dynamically resizable array is another name for a linked list. d. Any type of list tends to be better than an array when there are a set number of maximum items known beforehand. e. If many deletions at any place in the structure were common, a linked list implementation would likely be preferable to an arrayExercise B: "Matrix Addition" For this exercise you will design and implement a function that takes two matrix arguments and computes their sum (if and only if a sum can actually be computed, returning an empty list otherwise). Two matrices can only be added together if they have exactly the same dimensions. If the dimensions are acceptable, then the matrix sum will have the same dimensions as either of the operands, and the value of each element in the matrix sum is itself the sum of the corresponding elements in the operand matrices. And although it does makes sense to test rectangularity before attempting addition, you need not perform this step (since you did it above). In order to complete this task, you will need to: ensure you know how matrix addition can be performed² ● Your submission for this exercise:Old MathJax webview Old MathJax webview In Java Some methods of the singly linked list listed below can be implemented efficiently (in different respects) (as opposed to an array or a doubly linked list), others not necessarily which are they and why? b. Implement a function to add an element before the first element. c. Implement a function to add an item after the last one element. d. Implement a function to output an element of the list. e. Implement a function to output the entire list. f. Implement a function to output the number of elements. G. Implement a function to delete an item. H. Implement a function to clear the entire list. I. Implement functionality to search for one or more students by first name, last name, matriculation number or course of study. J. Implement functionality to sort the records of the student, matriculation number and course according to two self-selected sorting methods.
- Do not use 2d lists, sets, dicts, arrays or recursion. Code in Python. Write the function destructiveRemoveRepeats(L), whichtakes a list L and destructively returns a new list in which any repeating elements in L are removed. Thus, this function should directly modify the provided list to not have any repeating elements. Since this is a destructive function, it should not return any value at all (so, implicitly, it should return None). For example: L = [1, 3, 5, 3, 3, 2, 1, 7, 5] destructiveRemoveRepeats(L) assert(L == [1, 3, 5, 2, 7])Write a Python Code for the given function and conditions: Given function: def insert(self, newElement) Pre-condition: None. Post-condition: This method inserts newElement at the tail of the list. If an element with the same key as newElement already exists in the list, then it concludes the key already exists and does not insert the key.Write a function with below starting function: public static void printFirstAnd Last(ArrayList list) The approach should accomplish the following: Print "no elements" if the list is empty. Print the single element in the list if there is only one. Print the first entry in a list with more than one element, followed by a space, and then the last element.
- Add the following functions and write a program to test these functions in the class linkedListType: a. Write the definition of a function that returns the data of the kth element of the linked list. If such element is not exist in the list, exit the program. b. Write the definition of a function that deletes the kth element of the linked list. If such element is not exist in the list, exit the program and display message as output. (Subject:Data stracture and algorithm )QUESTION: NOTE: This assignment is needed to be done in OOP(c++/java), the assignment is a part of course named data structures and algorithm. A singly linked circular list is a linked list where the last node in the list points to the first node in the list. A circular list does not contain NULL pointers. A good example of an application where circular linked list should be used is a items in the shopping cart In online shopping cart, the system must maintain a list of items and must calculate total bill by adding amount of all the items in the cart, Implement the above scenario using Circular Link List. Do Following: First create a class Item having id, name, price and quantity provide appropriate methods and then Create Cart/List class which holds an items object to represent total items in cart and next pointer Implement the method to add items in the array, remove an item and display all items. Now in the main do the following Insert Items in list Display all items. Traverse…[] [] partite_sets In the cell below, you are to write a function "partite_sets (graph)" that takes in a BIPARTITE graph as its input, and then returns a single list whose two entries are the partite sets of the graph as lists (the order of the sets outputed does not matter). After compiling the above cell, you should be able to compile the following cell and obtain the desired outputs. print (partite_sets({"A" : ["B", "C"], "B" : partite_sets({"A" : ["B", "C"], "B" : ["A"], "C" : ["A"]}), ["A", "D"], "C" : ["A", "D"], "D" : ["B", "C"]})) This should return [["B","C"], ["A"]] [["A","D"], ["B","C"]] (the order in which the entries appear does not matter) Python Python
