此題與上一題類似，一次AC;
由于控制臺屏幕太小 這次我將結(jié)果保存在文件中；
#include<iostream>
#include<cmath>
#include<algorithm>
#include<cstdlib>
#include<cstdio>
#include<fstream>
using namespace std;
char mymap[2500][2500];
int leftdot;
int rightdot;
int topdot;
int bottomdot;
void figure(int x,int y,int degree)
{
leftdot=min(leftdot,y);
rightdot=max(rightdot,y);
topdot=min(topdot,x);
bottomdot=max(bottomdot,x);
if(degree==1)
{
mymap[x][y]='X';
}
else
{
int dis=(int)pow((double)3,degree-2)*2;
figure(x,y,degree-1);
figure(x,y+dis,degree-1);
figure(x+dis,y,degree-1);
figure(x+dis/2,y+dis/2,degree-1);
figure(x+dis,y+dis,degree-1);
}
}
int main()
{
int n;
int i,j;
ofstream file;
file.open("test.txt");
while(scanf("%d",&n))
{
rightdot=-100000000;
leftdot=100000000;
topdot=1000000000;
bottomdot=-1000000000;
memset(mymap,' ',sizeof(mymap));
if(n==-1)
break;
figure(1,1,n);
for(i=leftdot;i<=rightdot;i++)
{
for(j=topdot;j<=bottomdot;j++)
file<<mymap[i][j];
file<<endl;
}
file<<'-'<<endl;
}
file.close();
return 0;
}
