Inserting a value in an unsorted linked list has the following big-O running time a. O (1) b. O (log n) c. None of the above d. O (n) e. O (n2)
Say the list P R I O * R * * I * T * Y * * * Q U E * * * exists.On a priority queue that is initially empty, U * E (where a letter signifies insert and an asterisk implies remove the maximum) is applied. Please list the letters that were returned by theDelete the most operations possible.
Please Use Java language Write a method “mergeQueueStack” that takes a queue as a parameter of type: Queue of integers and a stack as a second parameter of type: Deque of integers Remove all the items from the queue and remove all the items from the stack then add them to a LinkedList by alternating between an item from queue then an item from stack. Don’t assume initially both the queue and the stack have the same number of items. The method should return the linked list of type integers. Example: If queue has : 1,2,3,4,5 and stack has 10, 20, 30 (where 10 is at top of the stack) then the linkedList should contain: 1,10,2,20,3,30,4,5
Create a collection. Along with GETMAX, MAXSTACK offers the ADT commands PUSH, POP, and EMPTYSTACK and performs similar operations to a standard linked stack. The GETMAX function keeps track of the largest stack member. Can the collection be constructed using GETMAX, which only requires O(1) time complexity? don't copy old bartleby answer it's wrong
IN JAVA This triple-ended queue exercise can be found at https://open.kattis.com/problems/teque. The requirements for this program are compatible with those of the Kattis problem, so a solution should produce correct results when submitted on Kattis. The Triple-Ended QUEue supports four operations: push_back x: inserts the element x at the end of the TEQUE push_front x: inserts the element x at the front of the TEQUE push_middle x: inserts the element x so that the insertion index for x is (k + 1)/2 for a 0-based indexed TEQUE. get i: prints out the ith index element (0-based) of the TEQUE. The TEQUE will be implemented as a linked list. The usual implementation requirements apply along with a screenshot of the results from Kattis.

You have two numbers represented by a linked list, where each node contains a singledigit. The digits are stored in reverse order, such that the 1 's digit is at the head of the list. Write afunction that adds the two numbers and returns the sum as a linked list.EXAMPLEInput: (7-> 1 -> 6) + (5 -> 9 -> 2).That is,617 + 295.Output: 2 -> 1 -> 9.

Create a new Java class in a file named "ListPQ.java" that implements the Queue interface and uses the LinkedList provided by the JCF to implement a priority queue. Note that LinkedList does not automatically order values based on priority, so it will be up to you to make sure that values are removed in priority order. You should try to implement your priority queue as efficiently as possible - basic operations should run in constant or linear time. Your priority queue need only work with integers. Do not modify any of the provided code. //This is ArrayHeap (provided code) import java.util.Arrays; public class ArrayHeap implements Heap { private int[ ] array; private int size; public ArrayHeap() { array = new int[3]; size = 0; } @Override public void add(int value) { // add pt 1 if(size == array.length) { array = Arrays.copyOf(array, size*2); } array[size] = value; // sifting up int child = size; int parent = (child - 1) / 2; while(array[parent] > array[child]) { swap(parent,…
There is one stacks and one queue q and then following operations are performed upon these two. Push A, enqueue B, push C, pop, pop, enqueue D, push E, dequeue, enqueue F .What is the total number of elements, which are left in the queue and stack in the end.
Write a program that reads a line of text, changes each uppercase letter to lowercase, and places each letter both in a queue and onto a stack. The program should then verify whether the line of text is a palindrome (a set of letters or numbers that is the same whether read forward or backward). Cannot use <queue> Library, have to use queueADT class as shown in the below, "Queue Demo." Thank you, will up vote. #include <iostream> #include <cassert>using namespace std; template <class Type>class queueADT{public: virtual bool isEmptyQueue() const = 0; virtual bool isFullQueue() const = 0; virtual void initializeQueue() = 0; virtual Type front() const = 0; //Function to return the first element of the queue. virtual Type back() const = 0; //Function to return the last element of the queue. virtual void addQueue(const Type& queueElement) = 0; //Function to add queueElement to the queue. virtual void deleteQueue() = 0; //Function to remove…
For the Queue use the java interface Queue with the ArrayDeque classFor the Stack use the java Deque interface with the ArrayDeque classFor the LinkedList, use the java LinkedList class Also, when you are asked to create and use a Queue, you can use only those methods pertaining to the general operations of a queue (Enqueue: addLast, Dequeue: removeFirst, and peek() Similarly, when you are asked to create and/or use a stack, you can use only those methods pertaining to the general operations of a Stack (push: addFirst, pop:removeFirst, and peek() ) Your code should not only do the job, but also it should be done as efficiently as possible: fast and uses no additional memory if at all possible Questions Write a method “int GetSecondMax(int[] array)” . this method takes an array of integers and returns the second max value Example: if the array contains: 7, 2, 9, 5, 4, 15, 6, 1}. It should return the value: 9
