single ended queue

Queues are an important concept of the data structures and understanding their types … The data structure required for Breadth First Traversal on a graph is? One simply needs to understand how deque can made to work as a stack or a queue. c) Front = rear + 1 c) Ordered array A normal queue, if implemented using an array of size MAX_SIZE, gets full when? A data structure in which elements can be inserted or deleted at/from both ends but not in the middle is? Explanation: The functions of deque to tweak them to work as stack and queue are list below. d) Linked list Circular Queue is also known as ________ If the elements “A”, “B”, “C” and “D” are placed in a queue and are deleted one at a time, in what order will they be removed? Most queue implementations are in one of three flavors: slice-based, linked list-based, and circular-buffer (ring-buffer) based. FIFO(First-in-First-Out). b) Front = (rear + 1)mod MAX_SIZE The process to add an element into queue is called Enqueue and the process of removal of an element from queue is called "Dequeue". In computer science, a double-ended priority queue (DEPQ) or double-ended heap is a data structure similar to a priority queue or heap, but allows for efficient removal of both the maximum and minimum, according to some ordering on the keys (items) stored in the structure. c) Queue Also, slice based queues tend to only be single-ended. b) Square Buffer Double ended priority queue Last Updated: 20-05-2019. d) Linear tree a) Stack Discuss Queue-the dequeue process removes data from the front of the single ended queue Aptitude Questions in forum, Read answers, post your answer and get reviewed from visitors. a) Ordinary queue View Answer, 6. Doubly Ended Queue (Dequeue) Image Source. Slice-based queues tend to waste memory because they do not reuse the memory previously occupied by removed items. Sanfoundry Global Education & Learning Series – Data Structure. c) Dequeue c) Tree On this Queue section of page you will find the easiest quickest ways to solve a question, formulas, shortcuts and tips and tricks to solve various easiest methods to solve Queue Question Quickly. Every element in a DEPQ has a priority or value. Q4interview.com is a first own type of educational portal, which aims is to cater to provide companies interview questions, mock test & Job info to jobseekers. The doubly ended queue or dequeue allows the insert and delete operations from both ends (front and rear) of the queue. a) Rear = MAX_SIZE – 1 The following diagram given below tries to explain queue representation as data structure − As in stacks, a queue can also be implemented using Arrays, Linked-lists, Pointers and Structures. The process to add an element into queue is called Enqueue and the process of removal of an element from queue is called "Dequeue". Double Ended Queue is also a Queue data structure in which the insertion and deletion operations are performed at both the ends (front and rear).That means, we can insert at both front and rear positions and can delete from both front and rear positions. View Answer, 3. b) LIFO (Last In First Out) principle A double ended priority queue supports operations of both max heap (a max priority queue) and min heap (a min priority queue). A linear list of elements in which deletion can be done from one end (front) and insertion can take place only at the other end (rear) is known as _____________ a) Queue Participate in the Sanfoundry Certification contest to get free Certificate of Merit. a) FIFO (First In First Out) principle View Answer, 9.
