分别输入5个测试数据文件，分别采用冒泡排序、选择排序、插入排序和希尔排序进行排序。并对排序过程中关键字的比较和交换次数进行统计并打印显示出来，以此展现排序算法性能比较-Enter the five tests are data files, respectively, using bubble sort, selection sort, insertion sort and Hill sorting order. And compare the sorting process and exchange of the number of times the keyword statistics displayed and printed out in order to show the performance comparison sorting algorithms
