使用链表可以轻松实现Queue。在单链表实现中,入队发生在链表的尾部,项目的出队发生在链表的头部。我们需要维护一个指向要保存的最后一个节点的指针O(1)插入效率。 由于双向链表提供O(1)在两端插入和删除,如果我们想在链表的开头入队和在链表的尾部出队,请使用它。

2. 基于范围的for循环 (Range-based for loop):C++11引入了一种新的for循环语法,使得遍历数据结构(如数组、向量、列表等)变得更简单、更安全。基于范围的for循环会自动处理迭代器的创建和管理,使得你可以专注于对每个元素的操作,而不是遍历的细节。 以上就是C++11中与数据结构相关的主要特性。这些特性在实际编程...
For example, the system can send an unsolicited message using tpnotify() without the TPACK() flag, or an application can send a message using tpacall() with the TPNOREPLY() flag. If the message queue of the receiving program is full, the message is dropped....

Queue Priority queue 6.3 迭代器(Iterator) 自C++11起,我们可以使用一个range-based for循环来处理所有元素,然而如果只是要中找出某元素,并不需要处理所有元素。我们应该迭代所有元素,直到找到目标。此外或许希望将这个(被找到元素的)位置存放在某处,以便稍后能够继续迭代或进行其他处理。
