告诫后人\textbf {\large 告诫后人}

切记！写这种码农题的时候不要一直不停的写下去，要尽量写的简单易懂，不要写的让自己都看不懂！

写了这题我才知道拥有一个良好码风的重要性/kk我那天从下午三点写到晚上十一点，最后好不容易过了样例，交上去只过了样例1.../kk后来好不容易改了一些明显的错误以后，样例2还是从将近900多行的位置开始错......我今天又想起来这道题，发现当时的代码我自己都快看不懂了。于是在这里告诫后人。

这就是拥有一个坏码风的结果

我还决定放一下自己1000多行还停留在25分的代码，以此来警戒大家。我放自己的代码，已经不报任何的希望有人帮忙找错了，希望大家能吸取我的教训。 /ll
