大概是把下面这个矩阵重复10遍：
```
1 0 0 0 0 0 0 0 0 0 0 0 0
0 1 0 0 0 0 0 0 0 0 0 0 0
0 0 1 0 0 0 0 0 0 0 0 0 0
0 0 0 1 0 0 0 0 0 0 0 0 0
0 0 0 0 1 0 0 0 0 0 0 0 0
0 0 0 0 0 1 0 0 0 0 0 0 0
0 0 0 0 0 0 1 0 0 0 0 0 0
0 0 0 0 0 0 0 1 0 0 0 0 0
0 0 0 0 0 0 0 0 1 0 0 0 0
0 0 0 0 0 0 0 0 0 1 0 0 0
0 0 0 0 0 0 0 0 0 0 1 1 0
0 0 0 0 0 0 0 0 0 0 1 0 1
0 0 0 0 0 0 0 0 0 0 0 1 1
```

@[142857cs](/space/show?uid=35760) 抱歉，我不会构造数据qwq。不过现在缩小范围的话要全部数据重造感觉挺麻烦的，模板题还是不要那么毒瘤吧qwq

@[superMB](/space/show?uid=118265) 那个。。。答案是`No Solution!`吗。。我的DLX本地上`0.04s`跑完了。。
