Write a method of the ArrayBoundedStack class to swap the item at the bottom of the stack with the item at the top of the stack. Do not use any other stack methods in your code. The fields of the ArrayBoundedStack are:   protected final int DEFCAP = 100; // default capacity   protected T[] stack;              // holds stack elements   protected int topIndex = -1;      // index of top element in stack

Stack: push(x) adds x to top of stack pop() removes top element of stack and returns it size() returns number of elements in stack Select all options that allow for an efficient implementation based on the discussions from class. For any array implementation, you can assume the array is large enough so that making a larger one is not needed when pushing an item to the stack. Using an array with the top at the front of the array. Using an array with the top at the back of the array. Using a singly linked list with the top at the head of the list. Using a singly linked list with the top at the tail of the list. None of these choices allows for an efficient implementation of all methods.

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.

Explore the stack's capabilities when allowed to be itself.

The ADT stack lets you peek at its top entry without removing it. For some applications of stacks, you also need to peek at the entry beneath the top entry without removing it. We will call such an operation peek2. If the stack has more than one entry, peek2 returns the second entry from the top without altering the stack. If the stack has fewer than two entries, peek2 throws an exception. Write a linked implementation of a stack class call First_Last_LinkStack.java that includes a method peek2

stacks and queues. program must be able to handle all test cases without causing an exception Note that this problem does not require recursion to solve (though you can use that if you wish).

Project Overview: This project is for testing the use and understanding of stacks. In this assignment, you will be writing a program that reads in a stream of text and tests for mismatched delimiters. First, you will create a stack class that stores, in each node, a character (char), a line number (int) and a character count (int). This can either be based on a dynamic stack or a static stack from the book, modified according to these requirements. I suggest using a stack of structs that have the char, line number and character count as members, but you can do this separately if you wish.Second, your program should start reading in lines of text from the user. This reading in of lines of text (using getline) should only end when it receives the line “DONE”.While the text is being read, you will use this stack to test for matching “blocks”. That is, the text coming in will have the delimiters to bracket information into blocks, the braces {}, parentheses (), and brackets [ ]. A string…

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   }   }

What is the operation that adds items to a stack? Get Set Pop Push

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…
