In simple linked list implementation of a stack, which end of the linked list may cause the worst run-time complexity of stack operations- select all that apply   a. inserting elements at the begining of the linkedlist while maintining a tail pointer   b. inserting elements at the begining of the linkedlist without having a tail pointer   c. inserting elements at the end of the linkedlist without having a tail pointer   d. inserting elements at the end of the linkedlist while maintining a tail pointer

Simple JAVA queue code implementation please help for any part, please be clear, thank you Given an interface for Queue- Without using the java collections interface (ie do not import java.util.List,LinkedList, Stack, Queue...)- Create an implementation of Queue interface provided- For the implementation create a tester to verify the implementation of thatdata structure performs as expected Wait in line – Queue (fifo)- Implement the provided Queue interface ( fill out the implementation shell)- Put your implementation through its paces by exercising each of the methods ina test harness- Add to your ‘BusClient’ the following functionality using your Queue-o Create (enqueue) 6 riders by name§ Iterate over the queue, print all riderso Peek at the queue / print the resulto Remove (dequeue) the head of the queue§ Iterate over the queue, print all riderso Add two more riders to the queueo Peek at the queue & print the resulto Remove the head & print the result§ Iterate over the…

1. Compare and contrast the implementations of the stack data structure using arraysand linked lists.a) How are they different?b) What are the run times of the stack operations for each implementation?c) When would one method be preferred over the other

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…

If a Stack is most optimally derived from a Singly Linked List, which node of the Linked List should be pointed to or will be referred to as the Top of the stack and why?

There is a data structure called a drop-out stack that behaveslike 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

solution for subpart 4

Write a push method for a stack implemented as a linked structure. You may assume that the implementation has the top element of the stack referenced by a LinearNode reference top and that an integer variable count keeps track of the number of elements in the stack. Hint: LinearNode class has a method called setNext which allows to reference a LinearNode object.

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
