CTSC/APIO2015北京游

也不是很清楚有什么意义。。希望不要滚粗就行了QAQ。。


4.27

打了两发BC和CF。。深深地自卑了QwQ。。。

英语又差智商又低。。连容斥都不会。。

今早睡了四个小时爬起来昏昏沉沉,模拟赛第一道COT5。。。

早就忘了楼房重建是个什么鬼。。搞了个看起来很对的CDQ分治套线段树调了5h。。蛤蛤。。

对自己无言以对。。。


4.28~30

頹狗的自我修养。。

基本没怎么刷题,下午打球发现自己已经不会打了TAT。。


5.1

劳动节耶。。

中午去外面吃了顿饭。。回到家里颓膈膜。。

和敦爷jabby大哥小j开黑下军旗。。

身为一个低端盘棋手被大哥小j的乱打各种打爆。。

大哥拿40撞窝地雷就问你怕不怕。

感觉节奏不对。。

撸点题把。。

模版又该背了

学习(抄袭)策爷和吉丽和Stilwell做了个blog音乐播放器> <


5.2

抵达北京

一切正常。。目测有高能人物在楼上。。


5.3

换房间。。喜闻乐见房主不退房。。等到下午一点。。酒店给我们换了房间。。

真是呵呵。。。


5.4

day1

一开始确实被第一题吓到了。。看看后两道。。两道计算几何即视感。。估摸着第二题可持久化平衡树套平衡树把,然而并不知道具体怎么做。。

只能去想第一题。。发现是水题。。码了。。但是由于好久不用linux。。不太会调程序。。代码能力奇渣。。先写了个SPFA,跑了1.7S大数据,换了个dij才过。。

然后撸第三题到结束。。

出来以后发现我第二题没有看到相交次数小于1e6这个条件。。。。。TAT。。知道的话感觉窝会去写KDtree。。因为并没有把握能写出标算。。

然后听说T1暴力又能过!。。。滚粗了。。。。。。

比赛的时候机房奇热无比。。

回去中暑了。。床上躺了三四个小时的样子。。


5.5

颓了一天。。


5.6

day2

并不会做T1啊。。取ln直接被吓傻了。。

看了一眼T2。。单次Onlgn的贪心已经被考烂了。。然后用线段树维护一下?好像就能做插入了?。。。

并没有仔细考虑删除。。直接上了CDQ分治。。调了4h。。还被卡常数。。

。。考后机智啊。。删除不是一样的吗T T。。。

爆零愉悦。。

还好最后T2受到Stilwell buff护佑低飞2.9S艹过去了T T。。

两天110,什么都没干,就知道报警,加起来还没人家一天高,还能Au,真是奇闻。

膜lyy 膜约大爷 膜杜教 膜J 膜劼


5.7

睡到11点被老大查水表了T T。。。


APIO

5.8

居然有讲课,讲的都是啥,zhx讲的东西还不错。。讲hash和K短路 = =。。。

颓模版。


5.9

开题,看看左边的人是APIO 2015而窝只有unofficial。。感觉不太对啊,把王老师叫过来。。

然后王老师教导我:你是B类选手,你比较弱,只能做unofficial!

原来是这样!

开场看T1,不会啊!1h+过去了,依然不会啊!

码了份暴力,咦他怎么是11。。淦!。。是或啊!说好的异或呢!。。

欲哭无泪。。然后发现前排吉丽四处张望,然后把vfk叫过来了,vfk做出膜膜膜的姿势。。。

然后。。然后。。吉丽拿上书包就走了O.O。。。惊呆了。。。。

劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼劼!!!!!

此时我依旧是0分。

看来是要爆零了。。

抱着滚粗的心态。。发现第一题换了题意就可以逐位确定了。。然后就会[tex]O(\log(2000*1e9)n^3)[/tex]了。。

发现有点卡空间。。用了个bitset,发现直接可以/32,然后。。就过了?

惊呆了。。

看第二题。。发现是个裸最短路啊,不过复杂度有点不对啊。。

反正爆零了。。写个暴力吧。。

然后。。就过了?

惊呆了。。

看第三题。。发现不会啊。。一座桥好像满足三分的?

当个暴力把。。

然后就过了一座桥的。

两座桥还满足吗?。。好像并不满足了?

不管了。。写一发试试。。

然后。。就63分了?

惊呆了。。

还是TLE?。。。

惊呆了。。

评测姬好傲娇啊。。怎么测一次就要pending半个小时啊。。

各种Error,under maintenance。。淦!

卡常数啊。。。

卡到5h还没卡进。。滚粗了。。还有三个记录在pending。。

日了狗了。。

然后延时了?

惊呆了。。

评测姬被调教过了?突然就不傲娇了?。。

然后又卡了几分钟。。就过了?。。

惊呆了。。

莫名其妙就AK了?。。

窝是暴力选手啊。。。。。。。。。。。。


5.10

跑去北大ACM。。一路跟着吉丽老司机,于是没有走弯路。。

看见皮球就在正前方,看起来好厉害啊。。

开场看C,这不是**题吗。。码了!

T了。。

卡常数。。。T again。。

敦爷把我赶走把A码了。。

然后我换了一种姿势开始码C。。

WA。。

T T。。。真的是。。。

敦爷把我赶走码I去了。。

突然脑子一抽。。会有超过K天或者小于1天的路径吗。。

灿爷说:会的。。

淦!改了一下。。WA again。。

T T。。被敦爷鄙视了。。

我又问:K会等于0吗。。

敦爷:显然不会啊!

灿爷看了看题目:好像会的。。

艹!改了一下。。过了。。然而一血没有了。。

看H。。这不是**题吗。。map直接上。

T again。。。

读入优化上。。过了。。。。。。

后来敦爷一直在做I。。做出以后说是**题。。我反正是不知道。。

4题就结束了。。绍兴一中的数学都很差,窝们并不会积分呀。。

滚粗愉快。。


5.11

就这么回来了。。

愉快的爆零经历呢!

省选加油吧。。

One thing I’d really like to comment on is that fat reduction plan fast is possible by the correct diet and exercise. Your size not merely affects appearance, but also the overall quality of life. Self-esteem, depressive disorder, health risks, along with physical capabilities are affected in excess weight. It is possible to do everything right and at the same time having a gain. If this happens, a condition may be the reason. While a lot food but not enough workout are usually accountable, common health concerns and traditionally used prescriptions may greatly increase size.
