The resulting Array Listmust be one element larger. Print the resulting list to the screen.c) In the same program, replace the element in the ArrayList at index 2 by null. Print the resulting list tothe screen.d) In the same program, remove the element at the last index of the Array List. Print the resulting list tothe screen.e) In the same program, use a 'for' loop to print each element of the Array List to the screen.f) Create a class named ArrayListManager. Into this class, code a method which prints to the screenevery element of an Array List of strings placed at an odd index. Hint: use a modulus.Exercise, maxCylinderVolume F# system function such as min or methods in the list module such as List.map are not allowed Write a function maxCylinderVolume that takes a list of floating-point tuples that represent dimensions of a cylinder and returns the volume of the cylinder that has the largest volume. Each tuple has two floating point values that are both greater than zero. The first value is the radius r and the second value is the height h. The volume of the cylinder is computed using ??2h. The value π is represented in F# with System.Math.PI. If the list is empty, return 0.0. Examples: > maxCylinderVolume [(2.1, 3.4); (4.7, 2.8); (0.9, 6.1); (3.2, 5.4)];;val it : float = 194.3137888> maxCylinderVolume [(0.33, 0.66)];;val it : float = 0.2257988304The function that will a single items to the list is Oextend (...)

Print all the values of the array after you execute clear using System.out.println(). what is the result of using clear function? 14. What is the shortcoming of using array List?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.Count dominators def count_dominators(items): An element of items is said to be a dominator if every element to its right (not just the one element that is immediately to its right) is strictly smaller than it. By this definition, the last item of the list is automatically a dominator. This function should count how many elements in items are dominators, and return that count. For example, dominators of [42, 7, 12, 9, 13, 5] would be the elements 42, 13 and 5. Before starting to write code for this function, you should consult the parable of "Shlemiel the painter" and think how this seemingly silly tale from a simpler time relates to today's computational problems performed on lists, strings and other sequences. This problem will be the first of many that you will encounter during and after this course to illustrate the important principle of using only one loop to achieve in a tiny fraction of time the same end result that Shlemiel achieves with two nested loops. Your workload…

Print the resulting list tothe screen.Focus on: Basic list operations, methods, use of functions, and good programming style Part 1. Write a program that does the following: 1. Create a list of length N where N is a randomly selected integer between 10 and 20 and whose elements are randomly selected integers between 0 and 19. 2. Print out the list. 3. Create a copy of the list. Sort the copy into decreasing order and print it. 4. Report the distinct elements in the list Before continuing with the next two parts, add a function user_input(lo, hi) to your program. It should ask the user for an integer between lo and hi and return the value. Use appropriate error handling and input validation. (You should already have one of these from back in Module 05) Part 2. Write a function named how_many(a_list, a_num) that that expects a list of numbers and a number as arguments. It returns how many times the number is found in the list. If the number is not in the list, return 0. For example how_many( [12, 15, 16, 4, 10, 3, 5, 7, 9,…Subject-Object oriented programing Write a program which:• creates a new Array List• adds 5 decimal numbers to it• prints the list to the screen In the same program, remove the element at the last index of the Array List.

- About initial programming in python: Create a function that receives as parameters a list of 4 elements [name,[phone(s)], email, instagram] and a phone number:• If the phone number is in the list, it must be removed.• If not, no updates will be made. Note: phone(s) is within another list. Your function should only return a Boolean value, indicating whether the change was made or not. To find out if the function did the phone deletion correctly, you should check the contents of the list with the contact details you used to test your function after executing it. In the image is the model of parameters, in this case the function must exclude from the list of 4 elements the indicated number '44322456' and return "True".@6 The Reference-based Linked Lists: Select all of the following statements that are true. options: As a singly linked list's node references both its predecessor and its successor, it is easily possible to traverse such a list in both directions. According to the terminology introduced in class, the head reference variable in a singly linked list object references the list's first node. According to the terminology introduced in class, in a doubly linked list, each node references both the head and tail node. In a double-ended singly linked list, the tail reference variable provides access to the entire list. In a circular linked list, the last node references the first node.In Python: Write a recursive function named Multiply2 that multiples by 2 and prints each element in a given list. For example: mylist=[1,2,3,4] Multiply2(mylist) prints: 2 4 6 8 Note: the function takes only one parameter, which is the list on which the operation will be performed. It's ok if the list becomes empty after calling the function.
