- A double-ended queue or deque is a generalization of a stack and a queue that supports adding and removing items from either the front or the back of the data structure. This assignment has two parts: Part-1 Create a doubly linked list based DeQueDLL class that implements the DequeInterface. The class skeleton and interface are provided to you. Implement a String toString () method that creates and returns a string that correctly represents the current deque. Such a method could prove useful for testing and debugging the class and for testing and debugging applications that use the class. Assume each queued element already provides its own reasonable toString method. Part-2 Create an application program that gives a user the following three options to choose from – insert, delete, and quit. If the user selects ‘insert’, the program should accept the integer input from the user and insert it into the deque in a sorted manner. If the user selects ‘delete’, the program should…Front and rear pointers are tracked in the linked list implementation of a queue. During insertion into the EMPTY queue, which of these pointers will change? (A Both front and rear pointer B Only front pointer Only rear pointer (D No pointer will be changedin 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 PYTHON Linked Lists Consider the implementation of the Linked list class, implement the following functions as part of the class: index(item) returns the position of item in the list. It needs the item and returns the index. Assume the item is in the list. pop() removes and returns the last item in the list. It needs nothing and returns an item. Assume the list has at least one item. pop_pos(pos) removes and returns the item at position pos. It needs the position and returns the item. Assume the item is in the list. a function that counts the number of times an item occurs in the linked list a function that would delete the replicate items in the linked list (i.e. leave one occurrence only of each item in the linked list) Your main function should do the following: Generate 15 random integer numbers in the range from 1 to 5. Insert each number (Item in a node) in the appropriate position in a linked list, so you will have a sorted linked list in ascending order. Display the…1 Implement a Queue Data Structure specifically to store integer data using a Singly Linked List. 2 The data members should be private. 3 You need to implement the following public functions: 4 1. Constructor: 5 It initialises the data members as required. 6 7 8 2. enqueue(data) : This function should take one argument of type integer. It enqueues the element into the queue and returns nothing. 3. dequeue(): It dequeues/removes the element from the front of the queue and in turn, returns the element being dequeued or removed. In case the queue is empty, it r 4. front (): 10 11 It returns the element being kept at the front of the queue. In case the queue is empty, it returns -1. 12 5. getSize(): 13 It returns the size of the queue at any given instance of time. 14 6. 1sEmpty(): 15 It returns a boolean value indicating whether the queue is empty or not. 16 Operations Performed on the Stack: 17 Query-1 (Denoted by an integer 1): Enqueues an integer data to the queue. 18 19 Query-2…TRUE or FALSE? Answer the following question and state the reason why: cout<<list.back()<<endl; = The back member function returns a reference to the last element in the list. In a Dynamic Stack, the pointer top stays at the head after a push operation. During a Pop operation in Static Stack, the elements are being moved one step up. In a dynamic implementation of stack, the pointer top has an initial value of null.
- Write java code for a member function insertSorted(int d) for a linked list. The function traverses the list until it finds the correct location, then it inserts a node in that location. You may use the function given the class.Write the functions, pop and push for a node based stack. Pop removes the top element (python)but does not return it. If the stack is empty, it should raise an exception.3. Define a function named stackToQueue. This function expects a stack as an argument. The function builds and returns an instance of LinkedQueue that contains the items in the stack. The function assumes that the stack has the interface described in Chapter 7, "Stacks." The function's postconditions are that the stack is left in the same state as it was before the function was called, and that the queue's front item is the one at the top of the stack. Use this Python template: class Queue:'''TODO: Remove the "pass" statements and implement each methodAdd any methods if necesssaryDON'T use any builtin queue class to store your items'''def __init__(self): # Constructor functionpassdef isEmpty(self): # Returns True if the queue is empty or False otherwisepassdef len(self): # Returns the number of items in the queuepassdef peek(self): # Returns the item at the front of the queuepassdef add(self, item): # Adds item to the rear of the queuepassdef pop(self): # Removes and returns the item…
- In C++, Write a program using linked list (not STL List) and mimic the stack push and pop operations in list's insert and delete functions. If you don't know about stack, stack follows Last In First Out (LIFO) pattern. Any item inserted in the stack first can be removed at last. Your linked list's insert and delete functions should insert the nodes in the linked list in such a way that the last inserted item could be removed first and first element could be removed last. For insertion, a node must be inserted from back end (not at head or middle) You can use the following structure for the node or any other of your choice. struct Node { int data; Node * next; }; Note: Write constructors (if applicable), use menu to offer choice to the user such as insert, delete, display , size and exit.Hii I need a C-Sharp\C# code for this Write a generic function, reverseStack, that takes as a parameter a stack object and uses a queue object to reverse the elements of the stack.A data structure known as a drop-out stack functions exactly like a stack, with the exception that if the stack size is n, the first element is lost when the n + 1 element is pushed. Use an array to implement a drop-out stack. (Hint: It would make sense to implement a circular array.)
