写在NOIP2018后
退役学了一周文化课,感觉还行吧
在周四就有学弟跟我说用我的源代码测329,当时还是出乎意料的.
本来期望是100+50+55+100+50+44=399,结果测得是100+55+50+100+20+4=329
一开始估摸着Day1写炸了结果想不到是把握很大的Day2,今天特意检查D2T2,T3代码发现都是傻逼错误
D2T2考场上用计数原理n=2时推出来f[i]=f[i-1]*4-f[i-1]/2*2
结果写了个这个狗东西:
for(ri i=3;i<=m;i++)f[i]=(f[i]*4%P-f[i-1])%P+P;
直接心态崩了
D2T3暴力就是一个简单的树形DP,没清空数组就从44变成4
70分全都败给了非智力因素
现在心情不太好,本来399还是有点搞头的,现在退役钦定了
想来还是自己太菜了,D1后面两道题都是有能力A掉的,也许是题目做得太少总是想偏想歪
终究还是自己的能力不够
文化课已经考了班上两次倒数,虽然之前也经常考竞赛班的倒数但滋味还是不怎么好受;
在新班认识的同学也多了两三个,还是很感谢他们还有一直陪伴着我的人
不管怎么说退役是注定的了,突然想到一首小学还是初中学过的诗:
Two roads diverged in a yellow wood, 黄色的树林里分出两条路
And sorry I could not travel both 可惜我不能同时去涉足
And be one traveler, long I stood 我在那路口久久伫立
And looked down one as far as I could 我向着一条路极目望去
To where it bent in the undergrowth; 直到它消失在丛林深处
Then took the other, as just as fair, 但我却选择了另外一条路
And having perhaps the better claim, 它荒草萋萋,十分幽寂
Because it was grassy and wanted wear; 显得更诱人,更美丽
Though as for that the passing there 虽然在这两条小路上
Had worn them really about the same, 都很少留下旅人的足迹
And both that morning equally lay 虽然那天清晨落叶满地
In leaves no step had trodden black. 两条路都未经脚印污染
Oh, I kept the first for another day! 呵,留下一条路等改日再见
Yet knowing how way leads on to way, 但我知道路径延绵无尽头
I doubted if I should ever come back. 恐怕我难以再回返
I shall be telling this with a sigh 也许多少年后在某一个地方
Somewhere ages and ages hence: 我将轻声叹息把往事回顾
Two roads diverged in a wood, and I— 一片森林里分出两条路
I took the one less traveled by, 而我却选择了人迹更少的一条
And that has made all the difference. 从此决定了我一生的道路
祝各位OIer好运
