Day 2 3.8
我只希望未来我赚的钱足够我支撑一个家庭,能够让我无忧无虑地玩电玩城,打台球。能够让我在想看单依纯演唱会的时候不会因为经济紧迫而放弃。要达到这些,没有金牌也大有机会。
说 D2,要从 D1.9 说起。
十点半了,该睡。但我就不睡。
不如你们试试,下面是歌词(象の一辈子)
Yeah, you could be the greatest/You can be the best/You can be the King Kong banging on your chest/You could beat the world/You could win the war/You could talk to God, go banging on his door/You can throw your hands up/You can beat the clock/You can move a mountain/You can break rocks/Someone call it practice/Someone call it luck/But either way you're going to the history book/
Standing in the hall of fame/And the world's gonna know your name/Cause you’re burning with the brightest flame/And the world's gonna know your name/And you'll be on the walls of the hall of fame
You could go the distance/You could run the mile/You could walk straight through hell with a smile/You could be the hero/You could get the gold/Breaking all the records they thought never be broke/Do it for your people/Do it for your pride/Never gonna know if you never even try/Do it for your country/Do it for you name/Cause there's gonna be a day/When you’re standing in the hall of fame/And the world's gonna know your name/Cause you’re burning with the brightest flame/And the world's gonna know your name/And you'll be on the walls of the hall of fame
Be a champion/Be a champion/Be a champion/Be a champion/On the walls of the hall of fame/Be students, Be teachers, Be politicians, Be preachers/Be believers, Be leaders/Be astronauts, Be champions, Be true seekers/Be students, Be teachers, Be politicians, Be preachers/Be believers, Be leaders, Be astronauts, Be champions/Standing in the hall of fame/And the world's gonna know your name/Cause you’re burning with the brightest flame/And the world's gonna know your name/And you'll be on the walls of the hall of fame/(will.i.am)Rap/Standing in the hall of fame.
成为——冠军!!!
D1 翻不了,D2 能吗?能拿分吗?
能每道题拿出手的分吗?
能每道题拿出手的暴力吗?
能每道题拿出手的特殊数据吗?
能每道题拿出手的 dp 、自动机或贪心做法吗?
甚至,再激进一点,能过一题吗??????
接下来我想放首歌,如果 A 了题就是《青春修炼手册》,否则就是《Hall of fame》。
这里。
棍母,应该永远是棍母了(因为 D2T1 我打了个 93.5 分询问 O(n+1) 次的做法)
快睡吧。看看这几年的题怎么拿分最重要。
没了。
我猜这时很多人会说:
“难道是信奥没了?”
“难道是这次考试没来?”
“难道是……”
别问了。
“没了”的意思是D2 的游记就暗含在上面的那句话里了。
是的,我在一道交互蓝题上耗了整整
剩下的题感觉也就只能一分不得咯。
没事的,
加油,明年继续。
对了,这道题可以这样做:
-
注意到在任意一般
n 排列a 中,Mex([a_i, a_j])=\min(\min_{k=1}^{i-1} a_k, \min_{k=j+1}^n a_k) 。 -
问题就此转化为求出
p 的前缀/后缀\min ,设它们分别构成俩数组x 、y 。 -
注意到
\forall i \in [0, n) 一定有x_i = 0 或y_i = 0 ,且必定存在i \in [0, n) ,有x_i = y_i = 0 。 -
最后处理的时候我一开始直接处理发现不行,得先把数喂给紧迫的。
于是这道题就做完了。为了只问
