- 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…Write a program and fill a queue with random numbers between 0 and 100. The size of thequeue is assumed to be 15. After filling the array with random numbers, display the elements in the queue and remove the elements of the queue and store these numbers according to the following criteria.If the number in the queue is less than 50, remove it from the queue and store it inside queue 2.Else, remove the number and store these values inside queue 3.Display all three queues on the screen.Take an Infix expression from the user and convert to a Postfix expression using Stacks. The use of pointers is not allowed.
- For the code shown in the screenshot below, draw a picture of the program stack when the function findSlope() is called the first time. You only have to draw the part of the stack for findZero() and findSlope().*in java* A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow. Word pairs consist of a name and a phone number (both strings), separated by a comma. That list is followed by a name, and your program should output the phone number associated with that name. Assume that the list will always contain less than 20 word pairs. Ex: If the input is: 3 Joe,123-5432 Linda,983-4123 Frank,867-5309 Frank the output is: 867-5309 Your program must define and call the following method. The return value of getPhoneNumber() is the phone number associated with the specific contact name.public static String getPhoneNumber(String[] nameArr, String[] phoneNumberArr, String contactName, int arraySize) Hint: Use two arrays: One for the string names, and the other for the string phone numbers.…Exercise 1: Write a program using the java.util.Stack data structure that prompts for an integer and reverses it: 7359 becomes 9537. Hints: Think of how base-10 works: A base-10 number is a sum of digit * 100 + digit * 101 + digit * 102, etc., where each digit in your number is that digit times a power of 10. Using that understanding, you can use modulo and integer arithemetic to get each digit and add it to a stack. Algorithm: Your number % 10 will give you the rightmost number. Example: 7359 % 10 = 9. Put the 9 on the stack. Now substract the 9 from original number: 7359 - 9 = 7350. Now take the 7350/10 to remove the zero. That is 7350 /10 = 735. Repeat the process, that is 735 % 10 = 5, put the 5 on the stack, substract the 5 and divide by 10. 730/10 = 73, use 73 % 10 to get the 3. Keep going, adding digits to the stack until you run out of numbers. When you pop the numbers off your stack, they will come off teh stack reversed. Note…
- Use an array and two index variables. Write functions or methods push, pop, and sizeof. Then write a main function or method that will allocate the stack at n=10 and push some strings in ii, print out the size, and then pop some strings from it. Note make stack be be able to hold string variable type. java1. Suppose you have the following array: {11, 22, 33, 44, 55, 66, 77}. Write a java program to find the sum of elements of the array recursively. 2. Suppose a program builds and manipulates a linked list: What two special nodes would the program typically keep track of? Describe two common uses for the null reference in the node of the linked lists. 3. Consider the following Java Code: What is the output when this code is executed? import java.util.LinkedList; import java.util.ListIterator; class Main { public static void main(String[] args) { LinkedList<String> myLList = new LinkedList<String>(); myLList.addFirst("Ali"); myLList.addFirst("Omar"); myLList.addLast("Sara"); ListIterator<String> myiterator = myLList.listIterator(); myiterator.next(); myiterator.next(); myiterator.add("Reem"); myiterator.previous(); myiterator.add("Ahmad"); myiterator.add("Khaled"); myiterator.previous(); myiterator.remove(); System.out.println(myLList); myiterator.next();…Implement a simple stack in java using the scenario below. A company wishes to keep track of the order in which it employed staff. Users can enter either "f" to fire, "h" to hire or "e" to end the program. When a member of staff is employed, their employee number is added to the top of a stack when someone has to be made redundant, the last person to join the company is removed from the top of the stack. Hint: Use ArrayList
- What is the best way to implement a stack or a queue so that it can hold an arbitrary number of elements? Select one: a. Using an array, and throwing an exception when the stack or queue is full. b. By creating a bigger array when the stack or queue is full, and copying the elements from the original array. c. Using linked lists to store the collection of elements.Write a recursive Java function displayOutIn that displays two items from an array list at one instance from out-to-in. until one or last two items displayed and the process stops. For example, given array A = {15, 74, 106, 10, 9, 86, 34} the displayOutIn function displays the following: 15, 34 74, 86 106, 9 10in c++ 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 the link list so that each items bill gets calculated (by multiplying quantity with price) and also calculate and display Total bill in…
