We continue to develop our Queue management system that we made in the previous module. You are asked to add a new functionality: adding two queues together. The result should be a new queue, where the elements of the first queue come first, followed by the second queue's elements. Given the Queue class, overload the + operator, so that the code in main works and successfully adds two queues.

- CODE IN JAVA You have probably heard about the deque (double-ended queue) data structure, which allows for efficient pushing and popping of elements from both the front and back of the queue. Depending on the implementation, it also allows for efficient random access to any index element of the queue as well. Now, we want you to bring this data structure up to the next level, the teque (triple-ended queue)!Hi! Currently stuck in a java problem and would appreciate the help! Question: You have probably heard about the deque (double-ended queue) data structure, which allows for efficient pushing and popping of elements from both the front and back of the queue. Depending on the implementation, it also allows for efficient random access to any index element of the queue as well. Now, we want you to bring this data structure up to the next level, the teque (triple-ended queue)! The teque supports the following four operations: push_back x: insert the element ?x into the back of the teque. push_front x: insert the element ?x into the front of the teque. push_middle x: insert the element ?x into the middle of the teque. The inserted element ?x now becomes the new middle element of the teque. If ?k is the size of the teque before the insertion, the insertion index for ?x is (?+1)/2(k+1)/2 (using 00-based indexing). get i: prints out the ?thith index element (00-based) of the teque.…Write a program for implementing queue using linked lists, for which you should use a structure to create a node with data and the next pointer. The program should be able to insert, delete and display nodes in the queue. The user will be asked to enter his choice either to insert a node (enqueue), delete a node (dequeue), display or to exit from the program.The options for the user should be as the following:1. Insert a node (Enqueue)2. Delete a node (Dequeue)3. Display4. Exit For example if user selected option 1 then the following should appear in the output:Enter the value to insert:Node is inserted If user selected option 2 then the following should appear in the output:Deleted Element is: If the user selected option 3 then the program should display the elements that are available in the queue The program will keep on running and taking inputs from the user until he selects the 4th option to exit.
- Programming Exercise 8 asks you to redefine the class to implement the nodes of a linked list so that the instance variables are private. Therefore, the class linkedListType and its derived classes unorderedLinkedList and orderedLinkedList can no longer directly access the instance variables of the class nodeType. Rewrite the definitions of these classes so that these classes use the member functions of the class nodeType to access the info and link fields of a node. Also write programs to test various operations of the classes unorderedLinkedList and orderedLinkedList. template <class Type>class nodeType{public:const nodeType<Type>& operator=(const nodeType<Type>&);//Overload the assignment operator.void setInfo(const Type& elem);//Function to set the info of the node.//Postcondition: info = elem;Type getInfo() const;//Function to return the info of the node.//Postcondition: The value of info is returned.void setLink(nodeType<Type>…ALL TRUE OR FALSE QUESTIONS 1. A "deque" allows an application to enqueue and dequeue from both front and rear of a queue. 2. The Queue ADT of the text is defined to hold elements of type Objec 3. Java supports inheritance of interfaces. 4. The text's array-based queue implementations use the fixed-front approach. 5. If N represents the number of elements in the queue, then the dequeue method of the ArrayBoundedQueue class is O(1). 6. When an object of class LinkedQueue represents an empty queue, its rear variable is 0. 7. A standard linked list provides a good implementation of a "Deque". 8. When implementing a queue with a linked list, the front of the queue is also the front of the linked list. 9. Our LinkedQueue class implements the QueueInterface interface. 10. The text's array-based queue implementations use the floating-front approach.Please implement the following problem in C++: Although a queue is "best" implemented with a list, it can be implemented with a vector if you take into account the starting position of the queue. For example, if five elements are pushed onto the queue, the start of the queue is at position zero and the end is at position 4. If we, then, pop two elements, the start would be at position 2 and the end at position 4. The two "popped" elements are not really removed from the vector, and that avoids the O(N) time problem for the pop function.Implement a class which uses a vector to store the queue. Be mindful of performance, such that if the queue is empty, the size of the underlying vector is "reset."
- Write a c program for implementing queue using linked lists, for which you should use a structure to create a node with data and the next pointer. The program should be able to insert, delete and display nodes in the queue. The user will be asked to enter his choice either to insert a node (enqueue), delete a node (dequeue), display or to exit from the program. The options for the user should be as the following: 1. Insert a node (Enqueue) 2. Delete a node (Dequeue) 3. Display 4. Exit For example if user selected option 1 then the following should appear in the output: Enter the value to insert: Node is inserted If user selected option 2 then the following should appear in the output: Deleted Element is: If the user selected option 3 then the program should display the elements that are available in the queue The program will keep on running and taking inputs from the user until he selects the 4th option to exit.1.3.14 Create a class called ResizingArrayQueueOfStrings that implements the queue abstraction using a fixed-size array. Then, as an extension, utilise array resizing in your implementation to get rid of the size restriction. 1.3.15 If standard input contains k or more strings, create a Queue client that accepts the command-line argument k and outputs the kth string from the last string located there.in c++ Write a function that takes a queue with 20 integer values and deletes the elements thatare between 15 and 20. In other words, only the elements less than 15 or greater than 20remain in the queue. This means that you need to have an auxiliary queue to store theelements between 15 and 20 and restore them back to the original queue.
- In PriorityQueue.java, write code for the following new functions:1. public boolean add( PriorityQueueNode x )This function adds a new node x to the priority queue. The node is added tothe heap by comparison of the rating attribute. It involves the “percolateup” process and returns true when finished. 2. public PriorityQueueNode remove( )This function removes the minimum element of the priority queue and returnsit. It involves a call to percolateDown( int hole ). 3. private void percolateDown( int hole )This function takes the position of the next available hole in the priority queueand uses it to bubble the elements through the heap until the heap property isrestored. 4. public void display( )This function prints out a formatted tree representation of the priority queueshowing only the rating of each node. The output should resemble that of atree. Tip: you may use the StringBuilder class and the Stringformat( ) method. Empty nodes in the tree can be replaced with “--”.Example output…The 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 in C++ language. You should not implement heapify or heapsort.…The program inserts a number of values into a priority queue and then removes them.
