- [tomato] 正确！ 02/09 15:36
- [crazyman] 没问题，继续努力。 02/03 15:13
- [younggay] 不错，完成任务，继续努力。 02/02 14:56
- [tomato] It's easy!No problem! 01/23 12:12
- [tomato] 嗯，这几道题都是比较简单的程序，仔细一点验证了结果是没有问题的。 01/23 11:43
- [younggay] 经测试，程序运行正确。 努力。 01/19 16:55
- [crazyman] 恭喜，加油。 01/18 17:34
- [crazyman] 没问题。继续。 01/18 17:32
- [mess] 能编写出来就是胜利，这个程序也耗费了很多时间吧^_^ 如果再编一次有多快呢，可以试试，一定会有 01/15 16:55
- [mess] 程序不难，不过加些注释，对子程序的说明就更好了。 01/15 16:52
