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…

ListQueue Node Node Node front= next next= next = nul1 rear = data "Thome" data "Abreu" data - "Jones" size - 3 The above is a queue of a waiting list. The ListQueue has a node (front) to record the address of the front element of a queue. It also has another node (rear) to record the address of the tail element of a queue. 4. How do you push a node with data, "Chu" to the above queue? front.next = new Node("Chu", front); a. b. front = new Node ("Chu", front) rear = new Node("Chu", rear) с. d. = new Node ("Chu", rear.next) rear Describe the reason of your choice. Your answer is (a, b, c, or d) Will the push action take time in 0(1) or 0(n)? Next Page Type here to search
How nodes are defined (struct node (value count left right) #:mutable #:transparent) Write in Racket (traverse n) A traversal of a BST is an algorithm for “visiting” all node in the BST. The traversal must visit each node exactly once. In the case of a linked list, a traversal is trivial since the structure is linear: start at the head, move to the next node, and stop when you reach the tail. In the case of a BST, traversal must account for multiple child nodes and keep track of which subtrees have already been visited and which have not. There are three types of traversal: in-order, pre-order, and post-order. We will only implement in-order. The in-order traversal of a BST has the property that the node values will display in ascending or sorted order. The function can be defined either recursively or iteratively. Recursion is much simpler, so we’ll stick to that. Recursive Algorithm for In-Order Traversal of BST parameter: node n, the root of the tree…

Radix Sorting Algorithm In C++, implement the radix sorting algorithm using a queue class.Steps: Create a queue filled with 10 random integers between 1000 and 9999. Next, create a list of 10 empty queues (0-9 digit bins), then dequeue each number from the main queue and enqueue them into the correct digit bin. Dequeue the numbers from each digit bin in order and enqueue them back into the main queue. Repeat the process for every digit (tens, hundreds, thousands, etc.) Finally, print the sorted list.
