common sense
(The picture above shows a bit similar to an index)
Although it looks like a double-ended array, it is not as fast as a single-ended array vector. The reason is that the continuity of its elements is maintained by the central controller. When accessing an element randomly You need to find the address from the central controller first, and then go to the buffer to find it. Of course, it also supports random access.

deque<int>d2(d1.begin(),d2.end());
deque<int>d3(10,100);//d3是10个100
