双端队列函数在实时使用中有哪些可能的应用？
What are the possible applications of deque functions in real time use?
帮助我学习实时使用集合库中的双端队列函数的应用，如果可能的话尝试添加一些例子。
谢谢。
docs for deque 本身指定了两个示例，假设提供了 maxlen：
Bounded length deques provide functionality similar to the tail filter in Unix. They are also useful for tracking transactions and other pools of data where only the most recent activity is of interest.
