Question
- Assume the existence of a class Queue whose implementation is unknown (array versus nodes), with operations enqueue, dequeue and isEmpty(). Write a Queue method void reverseQueue() that reverses the order of the elements contained in the Queue. You can assume the existence of any other ADT data structures and their operations.
- Assuming the following queue implemented using an array with wraparound
Redraw the queue after each of the following “consecutive” operations. In each case, show the contents of the queue as well as the positions of Front and Back.
(a) enqueue (3);
(b) dequeue ();
(d) enqueue (7);
(e) dequeue ();
(c) enqueue (5);

- 1. Write code to define LinkedQueue<T> and CircularArrayQueue<T> classes which willimplement QueueADT<T> interface. Note that LinkedQueue<T> and CircularArrayQueue<T>will use linked structure and circular array structure, respectively, to define the followingmethods.(i) public void enqueue(T element); //Add an element at the rear of a queue(ii) public T dequeue(); //Remove and return the front element of the queue(iii) public T first(); //return the front element of the queue without removing it(iv) public boolean isEmpty(); //Return True if the queue is empty(v) public int size(); //Return the number of elements in the queue(vi) public String toString();//Print all the elements of the queuea.

No other data structure can be used other than queues. The Queue must remain intact after finding the maximum value. Assume the class that has the findMax method implements Comparable.

For this question, make no assumptions about the implementation of MyStack except that the following interface methods are implemented and work as documented. Write a public instance method for MyStack, called interchange(T element) to replace the bottom "two" items in the stack with element. If there are fewer than two items on the stack, upon return the stack should contain exactly two items that are element.arrow_forward
- In python. Write a LinkedList class that has recursive implementations of the add and remove methods. It should also have recursive implementations of the contains, insert, and reverse methods. The reverse method should not change the data value each node holds - it must rearrange the order of the nodes in the linked list (by changing the next value each node holds). It should have a recursive method named to_plain_list that takes no parameters (unless they have default arguments) and returns a regular Python list that has the same values (from the data attribute of the Node objects), in the same order, as the current state of the linked list. The head data member of the LinkedList class must be private and have a get method defined (named get_head). It should return the first Node in the list (not the value inside it). As in the iterative LinkedList in the exploration, the data members of the Node class don't have to be private. The reason for that is because Node is a trivial class…arrow_forwardDesign an implementation of an Abstract Data Type consisting of a set with the following operations: insert(S, x) Insert x into the set S. delete(S, x) Delete x fromthe set S. member(S, x) Return true if x ∈ S, false otherwise. position(S, x) Return the number of elements of S less than x. concatenate(S, T) Set S to the union of S and T, assuming every element in S is smaller than every element of T. All operations involving n-element sets are to take time O(log n).arrow_forwardDefine the abstract base class LinkedSQD_Base using a linked implementation. Indicate whether each field and method should be public, protected, or private, and explain why. Implement each of the ADTs stack, queue, and deque as a class that extends your base class. Repeat parts a and b, but instead define and use the abstract base class ArraySQD_Base using an array-based implementation. Java programarrow_forward

- DisjointSet Class Implementation of this class is done in a1_partc.py A DisjointSet class represents a disjoint set which is a set of sets where every element can only belong to exactly one set. When a DisjointSet class is instantiated it is passed nothing and contains no sets. It make an empty Python dictionary which will be used to store the elements of the DisjointSet. The DisjointSet has the following member functions: def make_set(self,element) If element already exists within the Disjoint set, the function does nothing and returns false. If element does not exist in the DisjointSet, this function will add it to the DisjointSet by: make a new SetList object containing only one node, with the element as only value in the SetList adding a new dictionary entry where element is the key and a reference to the node containing element as the value return true Suppose we ran the following code: ds = DisjointSet() ds.make_set("cat") ds.make_set("dog") ds.make_set("fish")…arrow_forwardIn Java. The following is a class definition of a linked list Node:class Node{int info;Node next;}Show the instructions required to create a linked list that is referenced by head and stores in order, the int values 13, 6 and 2. Assume that Node's constructor receives no parameters.arrow_forwardThe program inserts a number of values into a priority queue and then removes them. The priority queue treats a larger unsigned integer as a higher priority than a smaller value. The priority queue object keeps a count of the basic operations performed during its lifetime to date, and that count is available via an accessor. In one or two places I have put statements such as op_count++;, but these are incomplete. We only count operations involved in inserting and removing elements, not auxiliary operations such as is_empty() or size() The class implements a priority queue with an unsorted vector. Your assignment is to re-implement the priority queue implementation using a heap built on a vector, exactly as we discussed in class. Leave the framework and public method interfaces completely unchanged. My original test program must work with your new class. You will have to write new private methods bubble_up and percolate_down. You should not implement heapify or heapsort. #include…arrow_forward
