目前本题没有人写出来 Python AC 正解，数据有问题。

@[L1833830873](/user/302194) 我也没做出来，可以参考一下
```python
from ctypes import *
libc = cdll.LoadLibrary("libc.so.6")
a,b,c,d = c_int(),c_int(),c_char(),c_int()
libc.scanf(b"%d%d%s%d",pointer(a),pointer(b),pointer(c),pointer(d))
for i in range(b.value):
libc.printf(b"%c",c);
libc.printf(b"\n")
t = c.value if d.value == 1 else b' '
for i in range(a.value - 2):
libc.printf(b"%c" + t * (b.value - 2) + b"%c\n",c,c)
for i in range(b.value):
libc.printf(b"%c",c);
```
~~确定不是C++吗~~
