Create a priority queue of integer values with duplicates. No more than 20 values.
Remove Duplicates
Write a method called removeDuplicates that accepts a PriorityQueue of integers as a parameter and modifies the queue's state so that any element that is equal to another element in the queue is removed. For example, if the queue stores [7, 7, 8, 8, 8, 10, 45, 45], your method should modify the queue to store [7, 8, 10, 45]. You may use one stack or queue as temporary storage.
kthSmallest
Write a method called kthSmallest that accepts a PriorityQueue of integers and an integer k as parameters and returns the kth-smallest integer from the priority queue (where k=1 would represent the very smallest). For example, if the queue passed stores the integers [42, 50, 45, 78, 61] and k is 4, return the fourth-smallest integer, which is 61. If k is 0 or negative or greater than the size of the queue, return -1 and print "Invalid Argument." You may use one stack or queue as temporary storage.
isConsecutive
Write a method called isConsecutive that accepts a PriorityQueue of integers as a parameter and returns true if the queue contains a sequence of consecutive integers starting from the front of the queue. Consecutive integers are integers that come one after the other, as in 5, 6, 7, 8, 9, etc., so if the queue stores [7, 8, 9, 10, 11], your method should return true. (Also return true if passed an empty queue.) If your method modifies the state of the queue during its computation, it should restore the queue before it returns. You may use one stack or queue as auxiliary storage.

- JAVA please Given main() in the ShoppingList class, define an insertAtEnd() method in the ItemNode class that adds an element to the end of a linked list. DO NOT print the dummy head node. Ex. if the input is: 4 Kale Lettuce Carrots Peanuts where 4 is the number of items to be inserted; Kale, Lettuce, Carrots, Peanuts are the names of the items to be added at the end of the list. The output is: Kale Lettuce Carrots Peanuts Code provided in the assignment ItemNode.java:arrow_forwardChange the insert and _insert methods accordingly to comply with the new format. - If a new word is inserted that has a matching sorted order of its letters as an existing Node, do not insert a new Node. Instead, modify the existing Node and append the inserted word into the list. Starter Code class Node: def __init__(self, value): self.value = value self.left = None self.right = None def __str__(self): return ("Node({})".format(self.value)) __repr__ = __str__ class BinarySearchTree: ''' >>> x=BinarySearchTree() >>> x.insert('mom') >>> x.insert('omm') >>> x.insert('mmo') >>> x.root Node({'mmo': ['mom', 'omm', 'mmo']}) >>> x.insert('sat') >>> x.insert('kind') >>> x.insert('ats') >>> x.root.left Node({'ast': ['sat', 'ats']}) >>> x.root.right is None…arrow_forwardIf front=2 and rear=5, how many elements are there in an array-based queue (note: rear is pointing at the next free location) O 3 4 2 5arrow_forward
- Add more methods to the doubly linked list class then test them• search(e) // Return one node with 3 values (stuID, stuName, stuScore) which matches agiven key e (studentID).• addAfter(e, stuID, stuName, stuScore) //Add a new node with 3 values (stuID,stuName, stuScore) after the node with the key e (studentID).• removeAt(e) //Remove a node which matches a given key e (studentID)• count() //Return a number of nodes of list.• update(stuID, stuName, stuScore) //Update the values of one node first code below package DlinkedList;public class DLinkedList<A,B,C> { private Node<A,B,C> header; private Node<A,B,C> trailer; private int size; public DLinkedList() { header = new Node<>(null, null, null); trailer = new Node<>(null, null, null); header.setNext(trailer); trailer.setPrev(header); } public int getSize() { return size; } public boolean isEmpty() { return size==0; } public A…arrow_forwardWe can declare a new array and copy the items of the old queue to new and by this, it will extend the size of the queue.arrow_forwardDONT use any of the list methods (append, pop etc.). class mycircularqueue(): def __init__(self, m = 10): self.maxsize = m self.array = [None]*m self.FRONT = self.REAR = -1 def enqueue(self, item): # Inserts item at the rear of a non full queue and returns True.
