（1）要模拟动态地显示出现题目中所要求的循环，我们要先建立两个循环队列。

（2）将数据分别存入这两个队列。以实现他们的循环配对输出，这是循环队列固有的特性。

（3）利用循环队列的特性，分别进行入队列和出队列操作，且实现搭配输出。

（4）循环队列的长度分别设为数据的个数即可。

-(1) to simulate the dynamic display required by the title appears cycle, we must first create two circular queue. (2) the data are stored in two queues. Match the cycle in order to achieve their output, which is the inherent characteristics of circular queue. (3) the use of circular queue characteristics, respectively into the queue and the queue operations, and to achieve with the output. (4) cycle length of the queue can be set to the number of data.
