其实本题严格来说是需要配置 $\rm spj$ 的，具体参考题目分数分布一栏：

If for some test case in which the solution to the puzzle exists, you output the correctly solved puzzle but your solution is not lexicographically smallest, you will get 40% of the points intended for that test case.

可见没有给出字典序而只构造一组解可以得到 $40\%$ 的分数，所以请求重新上传征集 $\rm spj$ 的标签。
