- In this task you will work with the linked list of digits we have created in the lessons up to this point. As before you are provided with some code that you should not modify: A structure definition for the storage of each digit's information. A main() function to test your code. The functions createDigit(), append(), printNumber(), freeNumber(), readNumber() and divisibleByThree() (although you may not need to use all of these). Your task is to write a new function changeThrees() which takes as input a pointer that holds the address of the start of a linked list of digits. Your function should change all of those digits in this linked list that equal 3 to the digit 9, and count how many replacements were made. The function should return this number of replacements. Provided codeYou are given an array-like data structure Listy which lacks a size method. It does, however, have an elementAt ( i) method that returns the element at index i in 0( 1) time. If i is beyond the bounds of the data structure, it returns -1. (For this reason, the data structure only supports positive integers.) Given a Listy which contains sorted, positive integers, find the index at which an element x occurs. If x occurs multiple times, you may return any index. Write code with explanationProblem 3: In classroom, we implemented MyStack by including an ArrayList as private data field of the class (using composition). In this problem, we will use another way to implement the stack class. Define a new MyStack class that extends ArrayList. Draw the UML diagram for the classes and then implement MyStack. Write a test program that prompts the user to enter five strings and displays them in reverse order. (1) Your UML diagram: (3)
- All the problems are to be coded in Python/Java. You must explicitly solve each problem below using your own logic. For example, Do not use existing library functions, such as sum( ), which computes the sum of a list. Instead, you must use for/while loop to sum up the items in a list. a. Write code for a CharList class which converts a string to a linked list of characters in the string. * b. Add a class member function which outputs if the linked list in Problem a. is a palindrome. What is the Big-O upper bound? c. What change could be made to the class definition in Problem a. to make your solution in Problem b. more efficient? Explain. What is the Big-O upper bound? Hint: Think of how the palindrome determination problem is solved for a regular string. d. Add a method to the classic List class we discussed in class that reverses the list. That is, if the original list is A -> B ->C, all of the list's links should change so that C-> B-> A. Make your solution as efficient as possible.…PYTHON:My program was supposed to identify the orders of the missing traversal, which is either the preorder or postorder. However, my program only works in identifying the PREORDER. There is something wrong with the function of my POSTORDER. Can you please identify the problem and fix it?

- MASM IRVINE 32 library PROGRAM. How do you take a SORTED array of elements and count the amount of each integer in that list and then display it. So if i had a list of [1,2,4,1,4,2,1,4,1,2,4,5,2]. I need to make a program that can iterate through that and find the amount of 1s, 2s, 3s, 4s etc and display it. MUST BE IN MASM IRVINE 32 LIBRARY.This is a c++ linked list question give me the answer quicklyWrite the main differences between Static and Dynamic Array List.
- You will create two programs. The first one will use the data structure Stack and the other program will use the data structure Queue. Keep in mind that you should already know from your video and free textbook that Java uses a LinkedList integration for Queue. Stack Program Create a deck of cards using an array (Array size 15). Each card is an object. So you will have to create a Card class that has a value (1 - 10, Jack, Queen, King, Ace) and suit (clubs, diamonds, heart, spade). You will create a stack and randomly pick a card from the deck to put be pushed onto the stack. You will repeat this 5 times. Then you will take cards off the top of the stack (pop) and reveal the values of the cards in the output. As a challenge, you may have the user guess the value and suit of the card at the bottom of the stack. Queue Program There is a new concert coming to town. This concert is popular and has a long line. The line uses the data structure Queue. The people in the line are objects…in this assignment i have to remove vowels from a string using a linked list. the linked list and link code is from a textbook and cannot be changed if the code alters the data structure. for some reason when i implement this code it gives me a logical error where the program only removes all instances of the first vowel in a string instead of moving through all vowels of the string and removing each one with all instances. i would appreciate if you could tell me the problem and solution in words and not in code.
