总结几个爱出问题的地方

Posted by hldyxh at 2008-07-28 12:28:58 on Problem 1002
1,对于大小写的处理
2,对于Q,q,Z,z,-以及各种非法字符的处理(直接跳过,忽视其存在即可)
3,对于号码000-0000的输出的处理
4,输出"No duplicates.",别忘了最后有一个点
5,考虑如下的输入:
   2
   1234567
   1-2-3-4-5-6-7

   能否得到输出
   123-4567 2

提高速度:我用的是C++,但是cin和cout太慢了,直接换scanf和printf。如果要排序,qsort()没有sort()速度快。
