There is a data structure called a drop-out stack that behaves like a stack in every respect except that if the stack size is n, then when the n+1 element is pushed, the first element is lost. Implement a drop-out stack using links.

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?

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

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…

Given a stack, a function is consecutive takes a stack as a parameter and thatreturns whether or not the stack contains a sequence of consecutive integersstarting from the bottom of the stack (returning true if it does, returningfalse if it does not). For example:bottom [3, 4, 5, 6, 7] topThen the call of is_consecutive(s) should return true.bottom [3, 4, 6, 7] topThen the call of is_consecutive(s) should return false.bottom [3, 2, 1] top The function should return false due to reverse order. Note: There are 2 solutions:first_is_conse cutive: it uses a single stack as auxiliary storagesecond_is_cons ecutive: it uses a single queue as auxiliary storage

A counter automaton is a pushdown automaton that only uses one stack symbol (in additionto the bottom of the stack marker). This means that the stack acts as a simple counter: the push operationincreases the counter, the pop operation decreases it, and you can check if the counter is currently set to 0by looking for the bottom of the stack. In particular, you can not store a string over an arbitrary alphabeton the stack. For example, the automaton for anbn we have seen in class is a counter automaton.Let L = {w ∈{a, b}∗|w contains the same number of symbols a and b}.(2.a) Build a counter automaton accepting the language L. As in Question 1, describe the algorithmused by your automaton, and draw a transition diagram.(2.b) Write down an accepting computation of your automaton on the string abbbabaa.
