Implement a function void printAll(void) to print all the items of the list.
The function swap_list_ends in python takes one parameter, L, which is a list. The function then swaps the first and last items in L and returns the object None. Notice that since L is mutable, the changes the function makes to L are visible back in the calling program.
SPECIAL CASE: If the list 'L' is empty, then the function does nothing to L and returns None.
For example:
Test
Result
L = [1, 3, 9, 2] if not(swap_list_ends(L) is None): print("Error: function should return None") print(L)
[2, 3, 9, 1]
L = ['super', 'awesome', 'excellent'] if not(swap_list_ends(L) is None): print("Error: function should return None") print(L)
['excellent', 'awesome', 'super']
L = [True, False] if not(swap_list_ends(L) is None): print("Error: function should return None") print(L)
[False, True]
This is needed in Java
Given that an ArrayList of Strings named nameList has already been created and names have already been inserted, write the statement necessary to delete the name at index 15.

- Can you help me please: Write a program to test various operations of the class doublyLinkedList. Your program should accept a list of integers from a user and use the doubleLinkedList class to output the following: The list in ascending order. The list in descending order. The list after deleting a number. A message indicating if a number is contained in the list. Output of the list after using the copy constructor. Output of the list after using the assignment operator.

- USING DOUBLY LINKED LIST in C Language In this project, you will implement a Polynomial ADT using Linked Lists. You will implement the Multiplication, Addition, and Subtraction operations of polynomials. Your program should be able to read a file of polynomials called equations.txt and store each equation in a doubly-linked list. Once the file is read and equations are loaded into the linked lists, the user should be able to perform mathematical operations on the polynomials (addition, subtraction, and multiplication). Once the user select an operation through a menu, the output should be displayed and then the menu should show again. Another option for the user is to store the results of all operations in a file called results.txt. Your application should show an appropriate screen with menu options to inform the user of the available operations to let her/him to choose from. Example of input file: 2x^7+10x^5-10x^3+2x+1 -15x^7-10x^5+90x^2-2 2x^2 + x - 1 Upon user selection, the…arrow_forwardAbout 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".arrow_forwardPlease make a JAVA program for the following: Use an array object to store the elements of the list object.
