java /* Practice Stacks and ourVector Write a java program that creates a stack of integers. Fill the stack with 30 random numbers between -300 and +300. A)- With the help of one ourVector Object and an additional stack, reorganize the numbers in the stack so that numbers smaller than -100 go to the bottom of the stack, numbers between -100 and +100 in the middle and numbers larger than +100 in the top (order does not matter) B)- (a little harder) Solve the same problem using only one ourVector object for help C)- (harder) Solve the same problem using only one additional stack as a helper */ public class HWStacks { public static void main(String[] args) { // TODO Auto-generated method stub }

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.

Create a programme that sorts a stack so that the smallest elements appear on top. You can use a second temporary stack, but you can't transfer the components into another data structure (such an array). The following operations are supported by the stack: push, pop, peek, and is Empty.

: 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.

Java Implement Stack using Deque (doubly linked list) You must create an array and the user can insert elements into this array and can only access or remove the newly inserted element from the array. The array is executed using a doubly linked list. The following Project should have these classes: 1. Class Book: The main Node for the deque array where it should have the following attributes besides (next, prev nodes): a) Book Id b) Book Name c) Book Author 2. Class Booklists: Where all the main operations are done. You need to apply these following operations: 1) AddBook() [push(0) : The method Inserts the book object into deque Stack (form the last). 2) RemoveBook() [pop()] : This method extracts an object from the last of the Deque stack and it removes it. If such object does not exist, the method returns null.(from the last) 3) isEmpty() : Return True if deque stack is Empty else return False. 4) DisplayAlIBooks() : Print all the books in the deque stack. 5) getlistsize(): Return…

10. Write a program which will rearrange and sort a stack of integer values, using two other stacks. The following algorithm describes how to do this: 1. Start with a stack of numbers named primary and two empty stacks named 1ower and higher. 2. Pop the first number from your primary stack and put it into the 1ower stack 3. Pop the next number from your primary stack, if it is smaller than the number you previously put into the lower stack, then add it to the lower stack, otherwise put it in the higher stack. 4. Repeat step 3 until the primary stack is empty. 5. Pop each of the elements from the lower stack and add them back into the primary stack. 6. Pop each element of the higher stack. If the value is greater than the value at the head of the primary stack, then add it onto the primary stack, otherwise add the number into the lower stack. 7. Repeat the process from steps 3 through to step 6 until both the higher and lower stacks contain no elements. At this point, the primary stack…

In java The following is a class definition of a linked list Node:class Node{int info;Node next;}Assume that head references a linked list and stores in order, the int values 5, 7 and 9.  Show the instructions needed to delete the Node with 5 so that head would reference the list 7 and 9.

OCaml Code: The goal of this project is to understand and build an interpreter for a small, OCaml-like, stackbased bytecode language. Make sure that the code compiles correctly and provide the code with the screenshot of the output. Make sure to have the following methods below:    -Push integers, strings, and names on the stack -Push booleans -Pushing an error literal or unit literal will push :error: or :unit:onto the stack, respectively -Command pop removes the top value from the stack -The command add refers to integer addition. Since this is a binary operator, it consumes the toptwo values in the stack, calculates the sum and pushes the result back to the stack - Command sub refers to integer subtraction -Command mul refers to integer multiplication -Command div refers to integer division -Command rem refers to the remainder of integer division -Command neg is to calculate the negation of an integer -Command swap interchanges the top two elements in the stack, meaning that the…

i want the program in 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…
