- 17 T OR F The QueueInterface interface represents a contract between the implementer of a Queue ADT and the programmer who uses the ADT.) i i RIS I i | il i i eue data structure in 4++ STL, push the following numbe: | pop 2 times from the ‘queue and print the elements in iAssume q1 is a queue created in the main and q2 is created in a block scope and we write q2=q1 and in the main function we print the items of the q1, if no operator= overload method then then Select one: a. The q1 has the same items of q2 b. The q1 items becomes rubbish c. The q1 becomes empty d. The q1 was not changed
- i) Create a Node class that will hold three fields i.e an integer element and a reference to the next Node along with a reference to the previous Node. ii) Create a Dummy Headed Doubly Circular Linked list Abstract Data Type (ADT)named DoublyList.The elements in the list are Nodes consisting of an integer type key (all keys are unique) and a reference to the next node and a reference to the previous Node. Use Python. Do not use NumpyUsing C++ . Create a queue using a linked list as your container and use a class. The system must have enqueue and dequeue operations and functions such as, isfull() and isempty(). Make sure it has an input and 10 data will be accepted.C++ Code for a QueueThe program should features a Queue class with insert(), remove(), peek(),isFull(), isEmpty(), and size() member functions.The main() program creates a queue of five cells, inserts four items, removes threeitems, and inserts four more. The sixth insertion invokes the wraparound feature. All the items are then removed and displayed. The output looks like this:40 50 60 70 80
- Project 4: Maze Solver (JAVA) The purpose of this assignment is to assess your ability to: Implement stack and queue abstract data types in JAVA Utilize stack and queue structures in a computational problem. For this question, implement a stack and a queue data structure. After testing the class, complete the depth-first search method (provided). The method should indicate whether or not a path was found, and, in the case that a path is found, output the sequence of coordinates from start to end. The following code and related files are provided. Carefully ready the code and documentation before beginning. A MazeCell class that models a cell in the maze. Each MazeCell object contains data for the row and column position of the cell, the next direction to check, and a bool variable that indicates whether or not the cell has already been visited. A Source file that creates the maze and calls your depth-first search method. An input file, maze.in, that may be used for testing.

- Create a Circular Queue Class and write a main() program to instantiate and use this class. You will use Arrays and Java PL for this implementation. Ensure that your class has the following attributes and methods: Attributes: rear, front and any others which you deem necessary Methods: queue(), enqueue(), dequeue(), isFull(), isEmpty(), peek()Write a C++ program to perform the Queue operation. Note:Use the following class template for Queue creation. template <class T>class Queue{ private: int front,rear; T *queue; int maxsize;}; Define the following function in the class Queue class Method name Description int isFull() The method is used to check whether the queue is full or not. void insert(T) The method is used to display the rear element in the queue (if the queue is stored with the element(s)). void deletion() The method is used to delete the front element from the queue. void atFront() The method is used to display the front element in the queue (if the queue is stored with the element(s)). void atRear() The method is used to add data to the rear end of the queue. void display() The method is used to display all the data in the queue. int isEmpty() The method is used to check whether the queue is empty or not. Input and Output Format:The first line of input…StackQueuePostfix A. Pointer_based queuea. Define the class PoiQueue with no implementation; i.e. declare the datamembers, and the function members only (Enqueue, Dequeue, IsEmpty,GetHead etc.).b.
