北京邮电大学数据结构实验三题目1

题目1

使用简单数组实现下面各种排序算法,并进行比较。

排序算法:

          1、插入排序

          2、希尔排序

3、冒泡排序

4、快速排序

5、简单选择排序

6、堆排序(选作)

7、归并排序(选作)

8、基数排序(选作)

9、其他

要求:

            1、测试数据分成三类:正序、逆序、随机数据

            2、对于这三类数据,比较上述排序算法中关键字的比较次数和移动次数(其中关键字交换计为3次移动)。   

            3、对于这三类数据,比较上述排序算法中不同算法的执行时间,精确到微秒(选作)

            4、对2和3的结果进行分析,验证上述各种算法的时间复杂度

编写测试main()函数测试线性表的正确性。
