Day 0
Itinerary: Take the bus from Hengshui to Texas and then transfer high-speed rail to Qinhuangdao.
I wanted to hit the computational geometry board before I started, but I didn't hit (flag).
When you get on the bus, parents have sugar. On the bus and third day driver (Zhangshiqi) decadent. Amway Bzoj's three Water problems (tribal division, maximum semi-connected sub-graph, minesweeper), Zhang's driver said he was frightened. So I said: The league must be more than these water (after hindsight proved that these three problems than this year's league simple to know where to go).
At the Texas high-speed railway station near a place called Yonghe soy milk to eat lunch. LED screen scrolling play "Xuanheng Citic Olympic athletes hit Blablabla" is also touching. (see the slogan I instantly feel that I will roll big thick 2333) to eat when the high school to learn the two points of the answer (transcription problem of test instructions break pulled a half a day to say understand, IQ 23333)
On the high-speed rail all sorts of decadent
Mob gambling (see NOIP2015D1T3). Played three laps, the card was taken away by the coach ...
Yang Shangyi played pⅴz and Pokemon were reported to the coach.
I looked at some of the results of the printing ... dizzy ... Abandon therapy.
In the hotel saw the stone two people. Got the legend of the fish and eggs, indeed delicious, than Heng Supermarket high to do not know where to go (I want to transfer do not stop me).
To Yanshan University test machine is also a joy. Constantly being organized from a computer room to another room ... Finally played for half an hour board. found that I will not million into the high-precision reading, virtual death.
"The keyboard of the examination room is too new I'm not used to it"-fyl
The evening continued to decay. Onlookers Yang Shangyi dozen pvz, eh ah yes swimming pool endless mode strong AH I will not ah. Read the print before you go to bed.
Day1
Morning get up good sleepy ... Roll it out. It's raining outside. Good to go to the examination room in the rain awake.
Entry is not allowed to operate computer 233. Can only play the board in spirit.
This year's compression package password is garbled 2333.
Unpack the package, T3 have bulk case. T2 gave a stack.pdf, mysterious and heavy.
Read the question. T1 send a sub-question. T2 ... What the heck? Sdoi the deformation problem of the tree? I don't have that problem, but I've read that it's a straight line of things covered in the path. Maybe it'll be a yy? Forget to look at T3 first.
T3 question surface Good God ... Expect? WOC League test expectations? It feels like it's going to roll. Forget to go back to code T1 first. It looks like a good code. Do not want to shoot, eye movement to check the wrong wave, feel no problem.
Another push for T2, as if it could be offline? Change the path overlay to a line that adds a corresponding intercept to each point on the path? The slope of the straight line to discuss the positive? A little trouble.
And looked at the T3, the original is the idiot DP. Before the application to walk after no aftereffect, class order is the natural DP sequence. F[i] said before I go to the location of the course, plus one-dimensional application of how many times, plus one-dimensional last class whether to apply, Floyd, casually DP, time complexity seems very stable. Fast code finished, over the bulk case. At this point there is also 2h. So happy to see T2. Push forward the positive solution seems to be very simple (flag), you can change each path on the LCA to split into two segments, then the modification is actually on the path at each point of a value equal to b+/-the number of the point depth, where B is the amount of the change itself. So you can change the difference on the tree to DFS again? So happily code code, the code to still remain 1h, suddenly found that the wording is not right. It's a lie. Fortunately, we finally got the method of subtracting the nearest ancestor from the same kind of inquiry. Shot in a sinister way. The hands were shaking when the exam was under.
The afternoon was gone.
Day2
Big Roll Coarse ...
T1 painting wind is still relatively normal, Yang Hui triangle take a post-modulo prefix and.
T2 only 65 points of the heap and then hit it first.
T3-like pressure. Because of the problem when the problem is somehow transformed into a geometric problem of the model, the result is to use the calculation of the geometry of the board, instantaneous virtual. The problem is I try yy calculate the geometry board also yy out. Maybe the code is not good, the code is 1h+, and ugly and long. Also did not shoot, eye movement wrong two waves + hand-made several data over, still less than 1h. At this time go back to engage T2, only more out q=0 and AI less than 10 million of 20 points. Finally change the priority_queue into a handwritten heap in case of Kathang. And there's no shot, pills.
100+100+100+100+85+100, but very afraid of the heart. In case of multiple sets of data initialization hangs, in case some strange place ce/re, in case of where the complexity of the wrong, I retired ...
Go back to the road continue to decadent.
day3+
Homecoming one weeks after class to participate in four notes (full name: Hengshui Middle School sophomore last semester, the fourth examination), the math test conic, Physics test electromagnetic induction, feeling and pills.
During the course of every day to sleep in thinking of where to explode int, where the wrong ideas. A week has gone by.
The league was divided before the four-tone. 585, a point did not hang, the province Rk1, the national rk30 aroundThis bear can also be saved rk1 visible he is a weak province.
It looks like he's got a lot of people hanging.
Yzya the d2t2, the strength AH.
A moment of silence for Gzz. D2t1 It should be 560 if you don't blow it up.
For this play, I feel more satisfied. Before the exam, I did not write a big search of the landlord, this time Noip did not test that question is my lucky place. D1t2 If I hadn't seen the sdoi problem, I didn't have the confidence to come up with a positive solution. Make up time I repeatedly tried to think d2t2 of the positive solution are not successful, visible in the examination room to give me more times I can only take 85 roll coarse, and q=0 20 points in fact is the first 5 minutes before handing over the yard, take very dangerous. D2t2 many people because of the Priority_queue card to 55, the handwritten pile inadvertently won 10 points. The last 15 points of d2t2, indeed beyond my ability.
Of course, some places are scared. If I have reviewed the calculation of the geometry of the board before the D2 half-court mentality will be much better. If the person who made the big search ...
It is probably the only pity that we have not strictly insisted on learning new things in the pre-exam training. If the practice CDQ divided the Board, the network Flow board, the Chairman tree, the slope of the optimization of the time used to do low test high-level thinking difficulty (this is the noip of this year's painting), I think the examination room may be a off d2t2. (now it seems that the league to write peaks-enhanced version is completely suicidal behavior) but people can not blame society, if not learn these new things maybe I will be in the noip of the examination room also break off the chain of thought. After all, the last year suddenly tested the tree chain to do the problem.
In short the exam process is very dangerous, compared to those strong province God Ben I was so weak to know where to go. Into the provincial team should not be a big problem, the national game is full of challenges, try it, such as the top of the blog, the big deal to go back to college entrance examination.It's going to take a one-month math paper (I don't feel like a provincial team).
Four tune did not out of grade 100, touching.

In general, compared to last year's topic emphasis on the investigation of knowledge points, this year's topic in the difficulty of thinking has a significant improvement, can effectively avoid "things to learn more, sub-high" situation. In my opinion, although NOIP is a popular form of the game, involving the knowledge point is limited, but does not mean that things to learn more can AK, competition competition, is the thinking, the game is the mentality, rather than just adhere to the study of the number of knowledge points, the length of study time. Let everyone have a harvest, this may be in my mind the game should be like it
