原理是临近的数字两两进行比较,按照从小到大或者从大到小的顺序进行交换,



这样一趟过去后,最大或最小的数字被交换到了最后一位,



然后再从头开始进行两两比较交换,直到倒数第二位时结束-The principle is close to the figure twenty-two comparison, in ascending or descending order of exchange, so a trip to the past, the biggest or the smallest number was traded to the last one, and then start over again pairwise comparison exchange until the end of the penultimate position
