• Queue
  1. The elements of the queue are processed in a FIFO manner.
  2. A queue is a convenient collection of reusable encoding keys that can be stored.
  3. Queues are typically used to implement a queued simulation.
  4. Point to the first element of the list, two references to the last element of the list, which facilitates the implementation of the queue list.
  The 5.enqueue and Dequeue Operations Act on opposite ends of the queue.
  6. Because the queue operation modifies both ends of the collection, the end is fixed at index 0.
  7. The non-circular array implements the element shift, which produces the complexity of O (n).
  8. Consider an array as a ring, eliminating the need to shift elements in the array implementation of the queue.

Last week's summary of the wrong quiz

• Common features should be located as low in a class hierarchy as is reasonable, minimizing maintenance efforts.
  A. True
  B. False
  Answer: B wrong solution: A
  Analysis: Public characteristics should be as high as possible in a reasonable hierarchy, the more public features, the less maintenance required.
