말뭉치

1. 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).
2. Here we will implement a double ended queue using a circular array.
3. A double ended queue also called as deque (pronounced as ‘deck’ or ‘dequeue’) is a list in which the elements can be inserted or deleted at either end in constant time.
4. In the computer’s memory, a deque is implemented using either a circular array or a circular doubly linked list.
5. In a deque, two pointers are maintained, LEFT and RIGHT, which point to either end of the deque.
6. In this dequeue,insertions can be done only at one of the ends,while deletions can be done from both ends.
7. Deque is sometimes written dequeue, but this use is generally deprecated in technical literature or technical writing because dequeue is also a verb meaning "to remove from a queue".
8. Nevertheless, several libraries and some writers, such as Aho, Hopcroft, and Ullman in their textbook Data Structures and Algorithms, spell it dequeue.
9. Allocating deque contents from the center of the underlying array, and resizing the underlying array when either end is reached.
10. The first one, called 'real-time deque, is presented below.
11. Also, the problems where elements need to be removed and or added both ends can be efficiently solved using Deque.
12. C++ STL provides implementation of Deque as std::deque and Java provides Deque interface.
13. A Deque can be implemented either using a doubly linked list or circular array.
14. Deque or Double Ended Queue is a type of queue in which insertion and removal of elements can be performed from either from the front or rear.
15. In this deque, input is restricted at a single end but allows deletion at both the ends.
16. Take an array (deque) of size n .
17. Check if deque is full If the deque is full, reinitialize rear = 0 .
18. That means in theory that an array with 1000 items is 1000x slower to do those operations than a deque with 1000 items.
19. The numeric slots of the deque object are internally used as an optimization and have no meaningful order or meaning to outside.
20. A deque, also known as a double-ended queue, is an ordered collection of items similar to the queue.
21. What makes a deque different is the unrestrictive nature of adding and removing items.
22. Definition - What does Double-Ended Queue (Deque) mean?
23. An In-depth Tutorial on Deque or Double-ended Queue in C++.
24. The difference between Queue and Deque is that it does not follow the FIFO (First In, First Out) approach.
25. Insert or add an item at the front of the deque.
26. Insert or add an item at the rear of the deque.
27. : Insert an element at the front of the Deque.
28. : Insert an element at the back of the Deque.
29. This method returns the first element of the Deque same as front method.
30. This method returns the end element of the Deque same as peek method.
31. In this image, there are currently 3 items in the double ended queue - the extra spaces on the sides are only there to show where new items can go.
32. In a double ended queue, items can be added to or removed from both sides.
33. I am writing my own deque/double-ended queue program.
34. A double-ended queue is an abstract data type similar to an simple queue, it allows you to insert and delete from both sides means items can be added or deleted from the front or rear end.
35. A deque is an important data structure for achieving computational efficiency in a diverse range of applications.
36. As a deque grows, nodes can be dynamically allocated for the deque, and when the deque shrinks, nodes can be dynamically deallocated from the deque.
37. This design (called “HatTrick”) allows the same memory to be used repeatedly to hold the items of the deque, rather than requiring an allocation and release for each item.
38. The underlying data structure is linear, however, so the best re-use occurs when the number of pushes and pops on a specific end of the deque during a modest period of time are roughly the same.
39. The nameis short for "double ended queue" and is usually pronounced "deck".
40. This interface defines methods to access the elements at both ends of the deque.
41. When a deque is used as a queue, FIFO (First-In-First-Out) behavior results.
42. Elements are added at the end of the deque and removed from the beginning.
43. Deque is a special type of data structure in which insertions and deletions will be done either at the front end or at the rear end of the queue.
44. A Double Ended Queue is a data structure in which it is possible to insert and delete from both ends (front and rear).
45. Given an integer m, size of double ended queue, and n operations, implement the double ended queue.
46. The invention relates to implementing a double-ended queue in a memory arrangement.
47. The double-ended queue, also called a deque, is in a way a combination of a queue and a stack, to which elements can be added and from which they can be removed as in a queue and a stack.
48. A double-ended queue, however, is a queue where an element can be added to either end or removed from either end.
49. In imperative (overwriting) environments, a double-ended queue can be implemented or realised e.g. as a double-ended linked list.
50. Strict and lazy implementations of Double-Ended Queue (aka Dequeue or Deque) based on head-tail linked list.
51. A double-ended queue (dequeue or deque) is an abstract data type that generalizes a queue, for which elements can be added to or removed from either the front or rear.
52. Deque differs from the queue abstract data type or First-In-First-Out List (FIFO), where elements can only be added to one end and removed from the other.
53. An output-restricted deque is one where insertion can be made at both ends, but deletion can be made from one end only.
54. You can use Deque as a stack by making insertion and deletion at the same side.
55. A double-ended queue, or deque , supports adding and removing elements from either end of the queue.
56. A deque can be populated from either end, termed “left” and “right” in the Python implementation.
57. The end result is that the deque contains the input sequence in reverse order.
58. Similarly, the elements of the deque can be consumed from both ends or either end, depending on the algorithm being applied.
59. The word dequeue is short form of double ended queue.
60. das Einfügen oder Entnehmen eines Elements am hinteren Ende der Deque.
61. podrían implementarse fácilmente con una deque.
62. o deque deve ser implementado segundo a abordagem circular, que confere eficiência à estrutura ao mesmo tempo em que evita o desperdício de memória.
