What is a Deque or double ended queue in data structure A deque, short for "double-ended queue," is a linear data structure that facilitates operations like insertion and deletion from both ends. It can be viewed as a broader version of a queue, offering increased flexibility. A deque perm...

A queue is a data structure based on the principle of 'First In First Out' (FIFO). There are two ends; one end can be used only to insert an item and the other end to remove an item. A Double Ended Queue is a queue where you can insert an item in both sides as well as you ...
A kind of method of the present invention for realizing double-ended queue (deque) in memory (MEM), a kind of configuration of memory. To can reduce duplication, especially in function environment, double-ended queue is used for rank of the memory as where go hierarchical data structure), ...
double-ended-queue x 14,425,547 ops/sec ±0.17% (94 runs sampled) node-deque x 2,815,628 ops/sec ±10.56% (76 runs sampled) built-in array x 19.23 ops/sec ±0.35% (51 runs sampled) Noteworthy is just how bad the degradation can be for built-in array when V8 cannot use the ...
Fast ring-buffer deque (double-ended queue) implementation. For a pictorial description, see the Deque diagram Installation $ go get github.com/gammazero/deque Deque data structure Deque generalizes a queue and a stack, to efficiently add and remove items at either end with O(1) performance....
At long last, let's get to that double-ended queue. Sorry for leaving you in suspense! Last time we came up with a non-solution -- as commenters immediately discovered, the given algorithm and data structure are deeply inefficient. However, the basicideais sound. There are ...
double-ended queues (deques); the first is implemented on a linear array, the second on a circular array. To our knowl- edge, all previous nonblocking deque implementations are based on unrealistic assumptions about hardware support for synchronization, have restricted functionality, or have ...
[11] developed effective algorithms to study a general double-ended queue with block-structure. The above mentioned works focused on the one-to-one matching, while matching with batch is more general and common in real life. For example, a taxi can match at most four passengers in the ...
The palindromic tree (a.k.a. eertree) is a linear-size data structure that provides access to all palindromic substrings of a string. In this paper, we propose a generalized version of eertree, called double-ended eertree, which supports linear-time online double-ended queue operations on ...
