One example where a deque can be used is the work stealing algorithm. [9] This algorithm implements task scheduling for several processors. A separate deque with threads to be executed is maintained for each processor. To execute the next thread, the processor gets the first element from the deque (using the "remove first element" deque operation).
Linked list. A doubly linked list has O(1) insertion and deletion at both ends, so it is a natural choice for queues. A regular singly linked list only has efficient insertion and deletion at one end. However, a small modification—keeping a pointer to the last node in addition to the first one—will enable it to implement an efficient queue.
Originally, only vector, list and deque were defined. Until the standardization of the C++ language in 1998, they were part of the Standard Template Library (STL), published by SGI . Alexander Stepanov , the primary designer of the STL, bemoans the choice of the name vector , saying that it comes from the older programming languages Scheme and ...

Double-ended queue (deque) Double-ended priority queue (DEPQ) Single-ended types, such as stack, generally only admit a single peek, at the end that is modified. Double-ended types, such as deques, admit two peeks, one at each end. Names for peek vary. "Peek" or "top" are common for stacks, while for queues "front" is common.
In combinatorial mathematics and theoretical computer science, a (classical) permutation pattern is a sub-permutation of a longer permutation.Any permutation may be written in one-line notation as a sequence of entries representing the result of applying the permutation to the sequence 123...; for instance the sequence 213 represents the permutation on three elements that swaps elements 1 and 2.
In linguistics, a calque (/ k æ l k /) or loan translation is a word or phrase borrowed from another language by literal word-for-word or root-for-root translation.When used as a verb, “to calque” means to borrow a word or phrase from another language while translating its components, so as to create a new word or phrase in the target language.
A calque / k æ l k / or loan translation is a word or phrase borrowed from another language by literal, word-for-word (Latin: "verbum pro verbo") translation. This list contains examples of calques in various languages.
