uva 10010 - Where's Waldorf?
https://uva.onlinejudge.org/index.php?option=com_onlinejudge&Itemid=8&page=show_problem&problem=951 题意:给出一个由大小写字母组成的二维maze...给出k个询问。每个询问一个单词。问能否在maze中找到这个单词。不区分大小写。输出开头字母的坐标(从1开始)。如果有多组输出最上面的。如果还有多组,输出最左边的。数据保证至少有一组。 思路:直接找就好了。。。坑的地方是。。。格式。。数据组数之后会有一个空行。然后每两组读入数据之间会有一个空行。。输出的时候每两组数据之间也有一个空行。
我因为一直多输出了一个空行一直wa QAQ
