这道题就是读懂题目太费劲了，非要扯到什么DNA上去，其实就是简单的数组处理，和上下左右的加加，然后查表把所得值加到当前项上来，若越界则处理下。

#include <iostream>
using namespace std;

const int  MAXNUM = 20;//培养皿是*20的大小
char SignTable[]=".!X#";//符号表  
int dish[MAXNUM][MAXNUM],res[MAXNUM][MAXNUM];   
int day,d[16];   

int main()   
{    
    int cases;//测试样例数  
    int i,j,k;  
    while (cin>>cases)
    {
        while (cases--)
        {   
            cin>>day; //培养天数
            //输入DNA序列信息
            for (k=0; k<16; ++k)
                cin>>d[k];
            //输入培养皿数据
            for (i=0; i<MAXNUM; ++i)   
                for (j=0; j<MAXNUM; ++j)   
                    cin>>dish[i][j];   
            while (day--)
            {

                    for (j=0; j<MAXNUM; ++j)
                    {   
                        k = dish[i][j];  
                        //和上下左右的结合起来
                        if (i-1>=0) 
                            k += dish[i-1][j];
