Its Mock Test provides a deep competitive analysis of your performance and points out your weak and strong areas, through intuitive graphical reports, which helps you to improve your skill. b) Simulation of arbitrary linked list 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 Explanation: Queue always has two ends. b) Array 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. It contains all the Data Structures topic Queue questions which are common in any of the preliminary exams of any company. Explanation: The process to add an element into queue is called Enqueue and the process of removal of an element from queue is called "Dequeue". A double ended priority queue supports operations of both max heap (a max priority queue) and min heap (a min priority queue). 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. Every element in a DEPQ has a priority or value. d) Tree Circular Queue is also known as ________ Doubly Ended Queue (Dequeue) Image Source. The doubly ended queue or dequeue allows the insert and delete operations from both ends (front and rear) of the queue. As we now understand that in queue, we access both ends for different reasons. A normal queue, if implemented using an array of size MAX_SIZE, gets full when? c) Circular queue d) Priority queue Queues are an important concept of the data structures and understanding their types … a) FIFO (First In First Out) principle c) DCAB c) Simulation of limited resource allocation This set of Data Structure Multiple Choice Questions & Answers (MCQs) focuses on “Queue Operations”. View Answer, 9. View Answer. Queues serve major role in ______________ Participate in the Sanfoundry Certification contest to get free Certificate of Merit. For the sake of simplicity, we shall implement queues using one-dimensional array. View Answer, 6. View Answer, 7. 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. d) Linear tree 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. Now, deque can be used to implement a stack and queue. View Answer, 2. c) Rectangle Buffer Most queue implementations are in one of three flavors: slice-based, linked list-based, and circular-buffer (ring-buffer) based. d) Curve Buffer b) Stack Which of the following is not the type of queue?
