随机函数产生一百，一千，一万和十万个随机数，用快速排序，直接插入排序，冒泡排序，选择排序的排序方法排序，并统计每种排序所花费的排序时间和交换次数。其中，随机数的个数由用户定义，系统产生随机数。并且显示他们的比较次数。(Random function produces 100,1000,10,000 and 100,000 random numbers, which are sorted by quick sorting, direct insertion sorting, bubble sorting, selection of sorting methods, and counting the sorting time and exchange times of each sort. Among them, the number of random numbers is defined by users, and the system generates random numbers. And show the number of times they compare.)
