This document provides an in-depth analysis of STD: deque and provides a guiding ideology: when considering memory allocation and execution performance, Using STD: deque is better than STD: vector.
Introduction
This article thoroughly studies
Deque double-end queue container (Object creation, access through arrays and iterators, element assignment, insertion, deletion, etc.), deque queue
Deque is very similar to vector. It not only inserts and deletes elements at the end, but also

In the past, we thought that the vector and deque were almost the same. In terms of efficiency, deque and vector were close, so we should simply use the efficient vector.However, if I ignore the other party, there is a reason for a transaction to
4-1 Deque (25 min)
A "deque" is a data structure consisting of a list of items, on which the following operations be Possible:push (X,D): In SERT item X on the front end of Deque D. Pop (d): Remove the front item from Deque D and return it. Inject

The deque dual-end queue container uses a linear table
The constructors of deque and vectors in STL, assign are basically the same, focusing on the characteristics of deque, the main differences between deque and vectors are as follows:
Deque is the data structure of a two-terminal queue, which can
Deque is very similar to vectors, where you can insert and delete elements at the end, as well as insert and delete headers. However, when considering the memory allocation policy and operational performance of the container elements, deque has
Deque is very similar to vectors, not only to insert and delete elements at the tail, but also to insert and delete them in the head.Only when considering the memory allocation policy and operational performance of the container element. Deque has
