Write a Java program that allow the user 1.Implement a queue in an array 2. Enter the following number 3,4,6,7,2,1,0) in the queue 3. Reverse the queue element using a stack to display them in this order (i.e. 0,1,2,7,6,4,3).

Write a Java program for a matrix class that can add and multiply arbitrary two dimensional arrays of integers. Textbook Project P-3.36, pp. 147 Implement Singly Linked List - use textbook Chapter 3.2 as an exaple. Write a main driver to test basic list implementations.

examine a very simple task: reversing a word. When you run the program, it asks you to type in a word. When you press Enter, it displays the word with the letters in reverse order. A stack is used to reverse the letters. First the characters are extracted one by one from the input string and pushed onto the stack. Then they’re popped off the stack and displayed. Because of its last-in-first-out characteristic, the stack reverses the order of the characters.

: Imagine a (literal) stack of plates. If the stack gets too high, it might topple.Therefore, in real life, we would likely start a new stack when the previous stack exceeds somethreshold. Implement a data structure SetOfStacks that mimics this. SetOfStacks should becomposed of several stacks and should create a new stack once the previous one exceeds capacity.SetOfStacks. push() and SetOfStacks. pop() should behave identically to a single stack(that is, pop () should return the same values as it would if there were just a single stack).FOLLOW UPImplement a function popAt(int index) which performs a pop operation on a specific substack.

In java how do you: Delete the lowest/smallest item from the Circular Linked List (provided the list is sorted in ascending order) Reverse a Stack S, using a Queue Q Add the top 2 elements of a Stack S. Return the addition and push the data back in the stack S. How to reverse a Queue using a Stack? How to reverse a Queue using an array?

Need help with this Java problems. Java files are attached. Add your code to the file ArrayStack2Lab.java. Add your tests to the main() method. Submit ArrayStack2Lab.java. Problem 1 Implement the method public void display() which displays the entries in a stack starting from the top. If the stack is empty, print "The stack is empty". Add the method to ArrrayStack2Lab.java. You do not need to modify StackInterface.java. Problem 2 Implement the method public int remove(int n) The method removes the n top most entries for a stack . If the stack contains less than n items, the stack becomes empty. The method returns the number of items removed. Add the method to ArrrayStack2Lab.java. You do not need to modify StackInterface.java.

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...

15. If a queue is implemented under an ArrayList, how much time does a queue add an item? a. 0(1) b. O(n) с. О(n2) d. 0(log n)

JAVA: Write a recursive method named threeSum that accepts a list of integers and prints all combinations of three integers in the list that sum to 0. For example, if given the list [-1, 0, 1, 2, -1, -4], print the following lines of output: [-1, 0, 1] [-1, 2, -1] [0, 1, -1] You may print the lines of output in any order. The elements in each three-element sublist should appear in the same relative order that they appeared in the original list. Do not print duplicate lists; if the same exact sublist can be made in multiple ways, print it only once. If there are no combinations of three elements that sum to 0, print no output. The list passed to your method must be back to its original state at the end of the call. Either do not modify it, or if you modify it, fully undo your modifications before the method returns. Constraints: Do not declare any global variables. You can use any data structures you like, and your code can contain loops, but the overall algorithm must be recursive and...

This is java. Write the java code that takes the contents of a stack and places it in a queue and takes the contents of a queue and puts it in a stack. Your code can only use stack and queue data structure. swapStackAndQueue(stack, queue) //method call This is java.
