@day -1@
THUWC heard the message held in December, suddenly stopped about a week and a half class (but only that afternoon).
(I know almost Question: How to evaluate THUWC2020 held in the winter of 2019)
Half weeks before feeling or training school, back suddenly became a training institution, and then arranged for a bit upset (because that is the day of training, we have only that afternoon = =).
The results suddenly told me to take good laptop before leaving, saying it was to go after the laptop test, the machine is not ready.
What this says is informal, no prizes, as has been previously took the (then I go Gansha ah Hey = =).
Then the coach told me to go to practice your skills exam, look at the time if they choose (write positive solutions to violence or write) of Mang what will get what results.
Well, when I went to draw water bar = =.
(In fact, I even wanted to write travel is not large, but the coach asked me to sum up, I have no idea = =)

Early in the morning by plane.
I heard that Beijing's low temperature to a few degrees below zero, so I can not help shivering Southerner.
Fortunately, the feeling on the plane, and even a few degrees below zero feel much better than this, the results just out of the cabin door put a scarf wrapped tightly 2333.
Mainly in the northern cold outside, go out on the feeling of cold, wind blowing, so the indoor heated indoor open hand, some warmer than the South.
(I am not a tricky question, ah, no I came to draw water ah)
Nothing you can do, go out for fun results have been let out in the afternoon. . . Before reviewing the hotel had not yet completed the review of network flow.
Out to dinner at night feeling cold wind blowing head is really impressive.
@day 1@
Morning reports collar dog tag. Looking for a long time only to find that the place is maintained building is reported. . .
How the results of the badge was written by Tsinghua Winter Camp 2019 ah.
Actually even made a scarf, I knew I would not bring a thing. . .
After completion report to the test machine. It is said that the test machine in question is THUWC2018 of the original title, not seen, can only try to cut the scene.
The first problem is a problem of water, after sorting the prefix and gone.
The second question how such a merger like a tree line, ah, do not want to write for a while to write, abandoned abandoned.
The third question seems to be greedy God string of questions. Looked at 10 o'clock, so wake up zjx big brother next door, went downstairs to find xmy Gangster go together.
(Zjx: you see that yl lk chiefs of me yet:? I face blind, did not recognize .zjx: His body is still very recognizable.)
Noon meal, we were told to be forced off the cushions and posed for the opening ceremony, the forced break in the hotel (it is not really want me to draw the water in the end it = = ... I thought I could go to listen to the wonderful opening ceremony content eh).
But look on the mind, it does not matter. This kind of thing is not the less appear.
Then in the afternoon start of the race, the official players than we start the race 35 minutes later, that is to say before the game finished 8:00. . .
Open question look at T1, very water, lower_bound about gone. A written a will, probably after just 20 minutes.
Then I began to see T2, lct dynamic feel like edged ring Erase tree maintenance. I feel very sick, I decided to go take a look at T3.
Then read the T3, it took a long time to read the questions, however, only the case of the chain (of course, violence) have a certain idea, completely lacks ideas.
And then decided to write T2, write positive solutions wrote half written a bit queasy, and then throw it again decided to write positive solution platter violence.
(Think of the game after feeling policies D1 of right or wrong ... that they listen to xmy examination room T2 someone wrote three hours lct the AC to the last, but I D1 than 200 points higher scores = 50s =)
(however .. to the D2 I think the strategy may D1 is also very good, if D1T2 like me, like to write D2T2 hung up, I estimate the fraction D1 is even more ugly = =)
(At this point you should probably try to go to the bathroom breath of fresh air?)
The results platter violence a better start, or write back several chain tree split. Finished, pay up, he hung up, attitude collapse = =. At this time a total of about half over.
T3 liver and then went to go try the case from the chain (only need to consider each point in front of the nearest point whether the distance> X) to expand, and then failed.
Think over 40 minutes just to think out of the case where X = 1 (only need to consider whether there is a father for each point), suddenly realized that wrong, feel that they should be the wrong direction. Finally abandoned the T2 T3 engage.
(Feel it again with the same CSP2019D1T3 problems ... not difficult to properly assess the results of a question a question of dead trapped inside get out ...)
First, T2 repair little bug, the finally divided over part of the tree. Little to restore a little confidence.
T2 then decide to write only a portion of the sub-tree of the base ring, and then finished, pay up, hung up = =.
Do not want to tune the tone for a while, abandoned title, engage in T3.
(OK third policy error at this time or do not engage in sub-section ring of the tree, or put out of tune that part, while the former was better look at some. Otherwise no good time to go and no achievement)
( in particular, because the last part of the chain of sub-T3 do not have time to write debugging hung up, the game is over)
Last = T3 = only 8 points.
Finished down just feel really full stroke = =.
Was going to say about the evening to play CF, the results came back to put this thing to forget. The water draw more memories recession Well = =.
@day 2@
Still for half an hour delayed opening test. To goo goo goo results to become delayed one hour open test.
Open question. See T1, one would aim in the n <= 15. Ah, yes like the right pressure. Feels like O (3 ^ n) of state pressure? But I feel that this Mozhe.
Glanced at T2, discovered quite like the dominant tree. Then glanced at T3, foundI don't need to think of the peach The title is a bit long, decisive Discard come back to see T1.
Starting from the section points. ai = 0 directly shaped pressure no problem, ci = 0 as the absolute value when transferring | x |, need to be considered when the positive and negative x transfer. Thought feeling when the symbol is determined, the absolute value or as large or as small as possible. Thus four memory states are represented <min 0 in / max and> 0 min / max.
Eh, eh, eh it seems to have one condition. the absolute value of ai, bi, ci of <= 15? This condition can be used to ensure that the range of weights. In addition, it should also be useful? Otherwise, just right to determine the range of values within the range of __int128 can do more of it.
Then I thought, and when an absolute value dp> 225, ci will not affect the positive and negative of it.
So -225 to 225 with a mark bool can scrape out whether, in addition to use that four state transition before you can think of it.Anyway, it is also dissatisfied with the card.
Then wrote a will too, and found that time has passed for an hour, a little nervous.
T2 looks like the dominant tree on the DAG, it seems I do not have to recall that weird seek methods dominate the tree of 2333.
Thought for a moment feeling can dominate the tree line tree merge, think again found that I might need to turn into a side point to do, he thought a moment and then prove some detail, so he began to write.
After finished naturally over the sample, and then pay up, and hung up = =. After only a middle b is the father and two points of n = m.
Tune for a long time, and did not find where the problem is. He wrote a violent segment tree instead of merging or not partially through the first set of points with the same ideas.
And then a little violence, wrote a direct marking then dfs procedures that govern the trees, the result was not before. What Well = =. . .
(Probably because my reasons are still troubleshooting with? Maybe then you should write a violence to try to beat)
Looked at one hour and a half left, control their desire to continue debugging forced change to T3.
Analysis of what the nature of the bubble sort, probably larger than if the front of their own, before switching to a position; otherwise the preceding exchange to the first position of greater than themselves.
In turn, I just need to count how many i meet before i pi is a big (denoted by cnt), and examine whether the last k were the largest, second largest, ..., k-large you can calculate the final answer.
If you know a little push cnt can be O (1) count.
Then write an O (n ^ 2) is calculated cnt program, had found no examples, then I need to find a special discussion has ordered all the circumstances, this time it's still sort the results after themselves.
Simply After 20-plus now. Think of the case of the chain should be used before the first segment tree maintenance bigger than its location, and the chain tree, then feel almost, but need to be discussed mansard path.
The thought of the discussion, I think yesterday D1T2, then began vomiting = =. . .
Then decided to continue the water, just hard D2T2, the end result of the game did not just come out = =.
Afternoon can finally go out and play, but only confined to the campus to play.
Had wanted to go on foot at the campus, the results began to go sour half feet, he decided to engage in a single Juji share a ride (feel very strange ah, a school around us are not).
As if the years have not ridden a bike, and others several times almost hit www.
By the way Tucao about my junk iPhone. . . Sudden shutdown did not say, after the boot drop from 50% to 10% of electricity consumption, and, in my rate of visible directly reduced to 5%. . .
I had wanted to listen to music while riding a bicycle to the. . . It seems that they want more ah. . .
The most irritating is that when I get back charging to restart hotel, it actually told me that there are 45% of electricity? ? ?
@day 2+@
Seemingly change their name to the day 3? But I still take the name of it. . . Otherwise easily be misunderstood.
Open the data look, ah? This time the topic is cache ah.Implying cards often have problems.
Half an hour to understand the basic concepts and structure of the subject material looked arrangement, seemingly independent of and T1 is very large analog disgusting, T2, T3, T4, T5 is a further step of the subject, which relies to achieve the former.
Determined to give up to write T1 T2 ~ T5.
T2 is the analog of a hash, a better portion of each type of sample can be measured are divided. He wrote all but written through the data points in the last part, the last part of the sub seemingly not quite nice implementation.
Then decided to write T3, then. . . Found himself at T2 or reconstruction of the code is better, no way to use part of the sub-ah Hey after not.
After the T2 code refactoring was more good-looking, he found himself in accordance with the process to say it does not seem right. After I found myself repeatedly confirmed the concept of cache and cacheline, confused. . . Only a cacheline T2 so there is no problem, but a plurality of T3 cacheline. . .
Then finally had to write about writing, then decided to put the last minute and took part again write T4.
Before writing T4 glanced at T5. It seems to have an additional paper?
Point to open a look. woc how are in English, as well as how woc 36, bye bye. So I do plan to go in the title T5 options.
Finally finished T4 left 10s, intend unexpected, and direct delivery.
Then pay, then the CE = =. . .
@day 3@
Teacher led a precaution, so get up early to see if there is no notice of the interview phone call came.
It was natural that did not. In addition to the already too outside, after all, I'm still full of the water, how to think such a thing is impossible ah = =.
Afternoon set the ticket, they have to find themselves shut out of the camp goo formula (woc the water so too the point of it ...)
Back then asked a question about the first-class xmy Gangster D1T3 how to do, he said there was no question of talking about links.
Shocked.
It seems I D1T3 probably never know how to do it = =. . .
Saying that this year, if D1T3 is also a data structure that, then, is not a four data structure that ah. . .
North winter camp that year can expect a six and a combination of the probability of counting, Tsinghua winter camp out four data structure that you have any questions
