一道很典型的最短路径的题目。
算法的思想来自于Dijkstra(迪杰斯特拉)算法，大家在这里对这个算法就不介绍了。
可以在学完最短经的算法后，用这道题目当做练手。。我的算法还需要优化一下，代码也需要优化，因为我的代码确实有点乱。。下面的代码仅供参考。。

#include <iostream>
#include <stdio.h>
#include <string>
#include <cstring>

其实，这道题目的意思简单的。
大概的意思就是，把找到每一个字符串出现的次数，然后，按照字典顺序把字符串和出现的次数依次输出来。。

鉴于这道题目的数据量并不大，所以，暴力解决就可以啦。。
所谓暴力，也就说，三重循环。。

#include <iostream>
#include <stdio.h>
using namespace std;

这道题目，其实不用怎么想，数据有大，不过一次遍历搜索就可以完成。
首先读入数据，储存在数组中，然后从数组的尾部向前面搜索判断，就可以了。。
#include <iostream>
#include <stdio.h>
using namespace std;
int main()
{
int t;
int n, m;
int r, c, w, h, cr, cc;
int left[109];
int right[109];
int top[109];
