Enqueue: The enqueue operation puts an element into the end of the queue. It is like standing in a line where whoever is the last to stand in is the first to be served. For example, if several documents are sent to some printer (placed in the queue of documents to be printed), they...
The Insert operation is called Enqueue, and adds an element to the end of the list; the Dequeue operation selects and removes its first element. As a result, the neighbors of the source node are generated layer by layer (one edge apart, two edges apart, and so on). As for DFS, ...

Enqueue(item T): Adds an item to the end of the queue. Dequeue() (T, bool): Removes and returns the item at the front of the queue. Peek() (T, bool): Returns the item at the front of the queue without removing it. Len() int: Returns the number of items currently in the que...
peek(): Without deleting it, returns the element at the front of the queue. It returns null if the queue has no items in it. add(E e): Adds an element to the end of the queue. Throws an IllegalStateException if the queue is full. remove(): Removes and returns the element at the...

Create a method to retrieve an element from a specific position: get(i) or even llist[i]. Create a method to reverse the linked list: llist.reverse(). Create a Queue() object inheriting this article’s linked list with enqueue() and dequeue() methods. Apart from being great practice...
在代码向NSOperationQueue 中加入命令对象后,运行例如以下动作: (1) 保持命令对象,这样其内存就不会被释放掉。 (2) 等待。直到队列头有可用位置。 (3) 当命令对象到达队列头时,命令对象的start 方法会被调用。 (4) 命令对象的main 方法得到调用。
