Input
The input begins with a single positive integer on a line by itself indicating the number of the cases following, each of them as described below. This line is followed by a blank line, and there is also a blank line between two consecutive inputs.The input begins with a pair of integers, m followed by n, in decimal notation on a single line. The next m lines contain n letters each; this is the grid of letters in which the words of the list must be found. The letters in the grid may be in upper or lower case. Following the grid of letters, another integerk appears on a line by itself ( ). The nextk lines of input contain the list of words to search for, one word per line. These words may contain upper and lower case letters only (no spaces, hyphens or other non-alphabetic characters).
Output
For each test case, the output must follow the description below. The outputs of two consecutive cases will be separated by a blank line.For each word in the word list, a pair of integers representing the location of the corresponding word in the grid must be output. The integers must be separated by a single space. The first integer is the line in the grid where the first letter of the given word can be found (1 represents the topmost line in the grid, and m represents the bottommost line). The second integer is the column in the grid where the first letter of the given word can be found (1 represents the leftmost column in the grid, and n represents the rightmost column in the grid). If a word can be found more than once in the grid, then the location which is output should correspond to the uppermost occurence of the word (i.e. the occurence which places the first letter of the word closest to the top of the grid). If two or more words are uppermost, the output should correspond to the leftmost of these occurences. All words can be found at least once in the grid.

苦战六小时 终于把这道B题拿下了 开始的时候 各种没输出 后来经过调试发现是 输入的时候有点问题 没有吧所有的数据都输入进去 看来以后需要好好注意输入数据的处理了
我身边的同学做这道题 都是用指针和八个函数 构思 代码看起来非常的清晰 但是本屌丝表示完全不会用指针和函数 所以干脆这样写了
#define TEST
#include <iostream>
#include<stdio.h>
#include<string.h>
#include<stdlib.h>
#include<ctype.h>
