替他发一下格式化过的代码（VS Code大法好）
```c++
#include <bits/stdc++.h>
using namespace std;
int dx[4] = {-1, 0, 1, 0};
int dy[4] = {0, 1, 0, -1};
int m, n, t = 0, x, y, d;
int a[50][50];
void asd(int e, int o)
{
int w = 1;
int dl[1000][3];
888888 a[e + 1][o + 1] = 2;
dl[1][1] = e + 1;
dl[1][2] = o + 1;
8888888 do
{
t++;
for (int i = 0; i <= 3; i++)
{
x = dl[t][1] + dx[i];
y = dl[t][2] + dy[i];
if ((x >= 0) && (x < d) && (y >= 0) && (y < d) && a[x][y] == 0)
{
w++;
dl[w][1] = x;
dl[w][2] = y;
a[x][y] = 2;
}
}
}
while (t < w)
;
return;
}
int main()
{
bool f = 0;
cin >> d;
for (int i = 1; i <= d; i++)
for (int j = 1; j <= d; j++)
{
cin >> a[i][j];
}
for (int i = 1; i <= d; i++)
{
for (int j = 1; j <= d; j++)
{
if (a[i][j] == 1)
{
asd(i, j);
f = 1;
break;
}
}
if (f)
break;
}
for (int i = 1; i <= d; i++)
{
for (int j = 1; j <= d; j++)
{
cout << a[i][j] << " ";
}
cout << endl;
}
return 0;
}
```
