还是先Refresh Day2吧。毕竟太弱

 

T1神奇化合物(compound) 不存在这样的原子序列 a1,a2,…,an (n>3) 满足 a1 与 a2、 a2 与 a3、 ……、an-1 与 an 以及 an 与 a1 都通过化学键相连,但它们之间却没有其他化学键相连的情况。<--求解释。顺便求qwer 857B程序。

写了3467B真是挺萌的。N倍杀= =。(跑的倒是还好)

 

T2:对不起,没有T2

T3爆0的金字塔(pyramid) 从左右/上下对称轴向两端长度/宽度非严格递减。 <--一开始题目没读懂完全错误的233,感谢zyhzyhzyh的帮助。

最终写了个若比的dfs居然还有10分。果然太弱。。

在约大爷的AK声中,我结束了这场战斗。
