If the program requires random access to elements, use a vector or a deque.<br /> 如果程序要求随机访问元素，则应使用 vector 或 deque 容器。<br /> If the program needs to insert or delete elements in the middle of the container, use a list.<br /> 如果程序必须在容器的中间位置插入或删除元素，则应采用 list 容器。<br /> If the program needs to insert or delete elements at the front and the back, but not in the middle, of the container, use a deque.<br /> 如果程序不是在容器的中间位置，而是在容器首部或尾部插入或删除元素，则应采用 deque 容器。<br /> If we need to insert elements in the middle of the container only while reading input and then need random access to the elements, consider reading them into a list and then reordering the list as appropriate for subsequent access and copying the reordered list into a vector.<br /> 如果只需在读取输入时在容器的中间位置插入元素，然后需要随机访问元素，则可考虑在输入时将元素读入到一个 list 容器，接着对此容器重新排序，使其适合顺序访问，然后将排序后的 list 容器复制到一个 vector 容器。<br />
