此程序能够实现从十个数中找出其中的最大值和最小值，全局变量在函数之间传递数据-This process can realize from 10 to identify one of a number of the maximum and minimum values, global variables in the function between the transmission of data

In computer science, a selection algorithm is an algorithm for finding the kth smallest number in a list (such a number is called the kth order statistic.) This includes the cases of finding the minimum, maximum, and median elements. There are worst-
