4.30

We had a holiday in the afternoon and we had to go to 12:00 noon for the game.

Then my father said he would come to pick me up, until more than two o'clock in the afternoon he arrived, and then in the dormitory of the building tube aunt is not open to me

I didn't go with the experimental class until I was three and a four.

A long time in the vicinity of the railway station found a hotel stay

Behind my father secretly bought a popsicle, feel very magnetic ah

The evening has been writing durian this problem of the standard, busy a long time to do the data

It was almost 10 o ' Cojs when the subject was passed on to the top of the bed, and then rushed to sleep with a hasty shower.

5.1

Early in the morning on the train, the car has been with the small friends to promote my cojs on the topic

After Beijing, do the subway to a forgotten name of the place, and then the teacher said to walk to the hotel, about two km

I felt nothing at first, only to find a bag in my hand after walking for a kilometer, my hands were purple.

Qaq regrets to lend his schoolbag to several Austrian students.

Difficult to walk to the hotel, and feel the environment is good

The only thing that was funny was that when I went to get my clothes, the teacher glanced at me and said L

Then he looked at me again, muttering as if he was a little fat, and then replaced me with an XL.

(And it's green!) )

In the afternoon to Beijing 80 test machine, feel the whole person overwhelmed

Guide does not match the parentheses it's disgusting.

Guide's compilation error why not automatically jump to the wrong line

How do you write guide's pat?

How to decide if you want to stop running after running the guide program?

Probably after 1.5 hours of confusion, finally will write program (cover face.

And then he went to dinner with Nathan.

Evening has been decadent 頽 decadent, decisive in the hotel in a bath, all over comfortably

And then use QQ to a few very important friends to beg the blessing, feeling is not very nervous

5.2

Exams, exams, early on by the teacher woke up

To Beijing 80 to solve the breakfast, then the teacher gave me the password strip

I'll go to the library and wait for the entry.

After meeting the yjz,% in the library, I asked the number of grandpa, he said he was 11th

I am number 12th, I save the election time and YJZ uncle next to, for Mao Ctsc also and YJZ uncle next to Ah

Then I do not know why my password bar is inexplicable disappeared, hurriedly to find the teacher to get a password

Entered, when the entry was silently% of several great gods

Issue a question, start to read the question

I heard that the first question problem, so the first look at the second question, after reading found a face can not be done

Forget it, write the violence first, and then start to write the violence. The second example

Feel oneself Emperor de Yao World, so continue to read the question, understand test instructions, change violence, change violence.

One hours after the opening, I was still writing the second 5-point violence, and still didn't pull it out.

Entry one-hour score: 0 Qaq

Then the Proctor changed the first question, I gave up the second question, decided to zero the second question.

To see the first question, read the question, did not understand what he was talking about

I read the question again, still did not understand what he was talking about

I read the question again.

Finally after looking at the topic for nearly 30 minutes, I finally succeeded in understanding the first question (my language died early.)

And then found that it seems to me in the Cojs myself yy of the topic is somewhat like, but put on the tree

But the solution of my own yy has not been written, but the theoretical time complexity, actually did not measure

Feel good guilty, and how to deal with the tree ah.

Think of it as if it looks like a sequence of DFS sequence offline processing of queries is just like a serial problem?

Look like you can do it, and then start writing

Entry two-hour score: 0 Qaq

My own YY practice is to use the Kd_tree query on the splay

Then the topic is similar to this one, and is also a two-time function and a

Since two things are not equivalent, it is possible to use the two-time function as the key value to maintain the splay.

Seemingly time complexity is a mystery (on the benefits of a big brain hole)

I probably wrote for half an hour with the guide, and then I tuned the compilation error for 20 minutes.

(I'm not familiar with Linux at all.) ）

Fortunately, whether it is splay or kd_tree I write very skilled, so over all the examples

Want to test 10w and 50w data, found that I actually forgot how to use the CTime clock function

So I had to pray that my brain hole was big and big, or I could run over 10w and get 50 points.

I did not even write the first question, the time is not measured (or Linux is not familiar with, and will not write.) )

Slightly stuck card constant ready to look at the third question

The intermediate Proctor changed the answer to the second example of the second question, which is exactly what I've been doing for one hours.

My answer is right from the start! I wasted one hours!

But still very happy, the second question finally has 5 points

Entry three-hour score: Qaq

Start preparing to play a question answer, the first point seems to be very regular appearance

Draw a picture to find the odd number of even below the figure, each query answer is a combination of

Then modulo the ghost animal is not a prime number and then lazy to write extended Lucas

Because up to 50000, decisively put the query out of sequence offline processing

Scrolling array recursive combinations number the first point of the mess.

To do the second point, found that the second point only since the ring has the right edge, the diagram is a chain

Push is a complete backpack, wrote a start to run

Then to do the third point, the third point is just the second point of the data-enhanced version

But because do not know how to open O2 under Linux and do not know how to open the background in Linux

I can only wait for the end of the second point of the answer, and so on when the next few points to glance at the

Found that the fourth point can be directly three-dimensional state random DP, and then the fourth point of the program to write

Waiting for the end of the 2nd program

Entry four-hour score: Qaq

The second point finally ran out and started running fourth point

found that the fifth point to the point of shrinking some points is the fourth point, so dragged over the fourth point of the program changed

Fourth point, run the fifth point of running.

It's about 20 minutes from the end of the exam.

I started running the third point, and the third point ran so slowly.

Wait, wait, ing.

Again to see the sixth point, found that they will do

200 points, Edge right is 1, this is not very sx matrix multiplication

But the third point is still running, I can't run the sixth point.

(Forgive this Konjac Konjac will not open the background under Linux, can only run one program at a time)
Looking at the seventh and eighth points, we found that the matrix multiplication was just a little bit bigger.

You can optimize it, but there's no time. Qaq

About 5 minutes left, I turned off the third-point program and found myself running 8w multiple answers.

Start checking the file name and so on, and the Proctor says the exam has been extended for 10 minutes due to the late hair curl.

Feeling the unusual sadness, then the sad I did the most stupid thing, I started to run the third point of the program

(In fact, if I was a little bit more witty, I could have started from more than 8w, or ran the sixth point, but I panicked)

And then a minute before the end of the exam, I turned off the third-point program, and it was a contrite departure.

Entry five-hour score: 102 (QAQ)

Afternoon has been waiting for results, the results of the library is too slow, I did not know that the results were pulled out to listen to the evaluation

I heard that the first question a dropped only seven or eight people, and the positive solution is what division + half plane

I heard that the second question some data points can find the law can be more than 10 points

I heard the third question, someone without picks FFT can get 86 points

It's a good lie in my heart.

To the library to see the results found themselves 152, instant peace of mind,

The first question inexplicably a, the second question 5 points, the third question 47 points

Summarize:

1, the test overall play good, RP very good, mainly because the first question oneself once yy wanted to have similar topic and gave not very good practice

But in the examination room to write out, in fact, the specific time complexity is still not analyzed, the third problem of each test point of observation done very good, but there are areas to improve

2, later only know day1 points I am non-training team players RANK1 Qaq

3, but planing to due to the game to correct the problem caused by the exam time one hours of waste, for the second question did not go to see the properties of each test point

And to think about whether you can get a higher score, this error is still quite large (but later busy answer estimates also have no time to find the law)

The third problem exposes many of their weaknesses, actually 86 points of the person's practice is the same as I do, but I was in the exam after half of the question of the beginning of the answer

And they will not open O2, not many programs run together, resulting in a lot of their idea is not to implement or not to run

It is worth mentioning that I test the third point of the error, if the mentality of steady, continue to run from the 8w will be able to run the end of the

And then the optimal decision is not to run the third point, but to run the sixth point, because that time probably can run out about 1000 of the data

It looks like a 4-5-point look.

What I regret more is that I did not turn over the last five points after 0 and then hand them over, so that my branch is a little higher.

Normal play should be 170+, but the first question hit me on the muzzle what can I say? Qaq

5.3

Training team's defense and Wang Xuan's World Report

I feel like I've heard a lot of heads.

But under the Taiwan remote% of your great God

One of them asked the curator how to look at Heoi out his original question

I feel the answer is still very magnetic.

Night has been in the dormitory decadent 頽 decadent, middle QQ chat when heard some bad news

So I wrote a blog in the middle of the night, the results did not stop the car, incredibly wrote for two hours, the middle write stop

It's two o ' sleep.

5.4

CTSC Day2

Due to the high day1, so their own day2 a little relaxed, resulting in day2 scores are various hanging up to fight

Actually still in the library, went in and found himself sitting on the right side of Beijing 80 sister Li Xingtong, feeling very nervous

began to read the question, read the first question, read the first question of the table, the person you are kidding me, this table is talking about

Take a look at the second question, ask for K, want to be sure, and find that you are not state-indicated

Look at the third question, why is the answer question Ah, Linux terminal is what Qaq

began to write the second problem of violence, and then started the card constant, hoping to run past the second and third point, card for about one hours or so

The first question randomly wrote a strange thing, self-proof found that each point does not have 3 points, but once the data >=250 will be T

So when I was >=250, I was randomly arranged.

began to play the third question, first thought of writing a violent look at how the output program (error ing)

After spending one hours looking for the Linux terminal where, finally in a sinister corner I found the terminal two word dot went in

According to the requirements to run the program, a satisfied

Soon every time simply looking for a path of violence finished, ran 10 points, found that there are more than 10 points

Then the first point of the hand, with more than 20 points

I began to blind yy, found that every time to find the longest way to engage in

Then, because of the violent process, my longest road was to use DFS (to become a common group of players)

All kinds of running, add a bit of strange pruning after finally made more than 30 points, discouraged ing

Next to Li Xingtong a face AK appearance, really scared the baby.

The last more than 70 minutes or so, probably because Day1 thought it was a big advantage.

I gave up the answer question, to see the first question of the table, see 20 minutes without fruit

And then went to the second question of the search for constants, so it ended day2

In the afternoon the library was very quick, and found the first question 18 points (randomly arranged all hung)

Second question 10 points (second point and third spread 0.3s card past)

The third question, 33 points, 61 points.

When the question was reviewed, I heard something Sancent:

I heard that the first question a big wave of people have dropped a (how they know the Latin phalanx is something

I heard the first question directly output 1-M 30 points

I heard that the second problem Kaka constant can pass the second and third point (and no card past

I heard the third problem for the longest road with SPFA on it (my mood is: WOC,SPFA Beg the longest road I unexpectedly did not think!

Day2 's achievement by each road master dry turned, became the 16th place, inexplicably on AU

Congratulations to Brother D1t1 and brother Xi a for getting AG.

One gold and two silver in a few copper, feeling seems stronger than last year Qaq

(When you come, you want to hit a violent, mixed cu.)

Summarize:

1, day2 error is too big, mainly day1 test good, so day2 some not too serious

2, d1t1 the Latin phalanx will not really be their own weak, but the output 1-m 30 points also want to let me spit groove

A lot of time in the exam is spent on the second problem of the card constant, the results did not get points, but also the cause of DAY2 score collapse

D2T3 's submission answer question did not think of using SPFA is his biggest mistake, for the graph theory knowledge can not do effective simplification model

Just think of what to do is also a major weakness of their own, but from the question given by the solution to see

I do not have a quiet heart to carefully observe each test point is also a big mistake of their own, because in fact, all test points do not need SPFA

3, I actually use the exam 1/5 time to find the Linux terminal where!

5.5

CTSC End Day, Apio registration Day

Stayed at the hotel for a day and went to the test machine in the afternoon

Find that you do not write interactive questions, and will not write under Linux

So now% of the brother, indefinitely wrote some interactive questions

Later in the evening continue to think about life on QQ

What has been taught to Eileen Chang's white Lotus red roses and other things like carnations

Feel very unhappy, I actually do not want carnations

It's hard to see.

CTSC the gold thing with mommy, Mommy said it was a surprise.

With a good friend said, friend reaction: lying trough! You're such a dick!

Oh, no words, ING.

You guys never really looked at me, Qaq?

5.6

I got up late in the morning and didn't catch the class

Listen to them at noon, say in the morning a bunch of what artificial intelligence, such as Oi unrelated things

Instantly lost the idea of going to class in the afternoon

So I stayed at the hotel for another day.

Evening with a lot of good friends chatting very high, unconsciously in the middle of the night

I heard there are uoj, but I don't know much about the gods.

and give up when you think about it.

Someone told me that you'll go through a hard-to-forget person, and then it'll be easy to forget everyone.

There are people who show me that winter vacation has a three-month holiday! Shameful..

5.7

Apio Test Day

Feel very nervous, in the middle of the corridor in the confusion of the password strip lost, fortunately, good people picked up

After entering the field, I found out that the driver was walking around the classroom and I thought he was the Proctor.

Then I found out that his badge was green, and then I looked around and found that only a few machines were empty.

And the one on my right is ZJ-032, and I was in a tight seat, and then the driver sat down on my right.

Mom, scared the baby, and hurried to% of the driver

After the exam began, enter to see the first question, think is a very simple DP

Then began to push, push, push, die or die, accidentally found next to the Kat driver to enter less than half an hour cut the first question

Feel good panic in the heart, and then go to die push the first question, pushed for two hours a little progress is not, had to write 31 points of violence

Then went to see the second question, found that the idea of the beginning of the problem is wrong, so had to write off 26 points of violence

Finally, there are two hours to do the third problem, the third is an interactive problem, found that 30 points can be done

So wrote a pitch, handed up CE, and changed the change, and CE

At that time my forehead of the cold sweat Zenzen down, after I began to look for how not CE method, and then various play terminal

All kinds of mess, finally in one hours after I found my mistake, hand it up, and then the evaluation machine stuck, no feedback results

King de Yao World.

At that time did not have the mood to do the first question, has been looking at the third question waits the result

After half an hour of wasting, I found there was no CE, but it was half an hour before the end of the exam.

Completely abandoned treatment, anyway, the evaluation machine also stuck, silently sat for half an hour after leaving the field

Feel the whole violence, the bronze medal is not guaranteed.

Next to the Kat driver entered the first question, then quickly took down the third question, then heard that he wrote the second nlog^2n practice, has been in the card constant

Finally, I'm sorry I didn't pass.

The end of the exam to the Kat driver's signature, feel even if the dog is worth it.

Lyc a dropped the first question, after the end he gave me an Amway, I understand how to do after the only constantly feeling their stupidity

The afternoon is really not in the mood to listen to the evaluation, I feel like a dog with

In the evening to see the Tsinghua Intelligent Body Contest, it is very lack of thought

See Qin uncle all kinds of poke wild strange chrysanthemum

See Zou ye-chi-eyed the wild monster

See the last great finals

And the man-machine wars that spit out the groove.

Finally out of time just brother's father Spit Groove Zou Uncle A look is very not pay attention to people, buttons are not buckle good

Often stay up late, the body is not good.

It feels like a standard programmer's pie. But Zou uncle's strength is still very strong qaq

I don't know if I've had a chance to play such a game, sentimental ing

5.8

Life in Beijing is almost over.

Morning to Peking University played a field ACM, and just brother, Lyc a team

I have been there blind BB, but there is no real contribution (except for the translation of the topic)

I eat steamed buns in the morning without full, hungry belly playing ACM

Take a look at the second, a very simple topic, found that we are the first a (do not know there is no title

And then to do J, because I'm very stupid element of the meaning of not figuring out that the random sentence caused WA three rounds (in fact, no need to judge the weight of the

Just brother said G many people a, seemingly can do, wrote a Dijkstra template on a

I see the C question someone has gone, went to see C, Lyc said is a digital DP, so we went to think of digital DP

And then brother just said let me write, I said I did not write a number of DP on the push to just brother

When I wrote the C question, I looked at the remaining six questions and felt that I could not do anything but D and H.

Then I and LYC went to see just brother's procedures to help him to check the wrong, changed about 10min handed a a dropped

After I finished writing C, I went to write the H question (naked no more naked matrix multiplication) with the complete idea.

Because of the reason of%lld wa a pitch, changed to cout on the off

This time the game has just started about three hours, our team on a dropped five questions, rank39

Then the tragedy came, we began to think about D, D is a structural problem.

In the middle of the lunch, we ate about 20min, I have the cheek to more than two bottles of water, then to encourage LYC to eat in the main points

As a result lyc would rather starve than yield, and finally had to give up

Three people have been thinking of D, the result is at

Watched one after another team a dropped the D question, their team's ranking all the way down

But I just can't think of D, looked at other topics, feel more can not do

There's only half an hour left, and three of us are starting to heal, rank60.

In fact, we've only been playing for three hours in this ACM? It's sad.

But good for lunch.

Afternoon back to the hotel for an afternoon, evening to attend the closing ceremony of Apio

Found himself so naked in the violence of the inexplicable AG, and felt very incomprehensible

We checked the gold medal number and the silver medal number.

found that if according to NOI's mechanism, he is the bronze mid-stream Qaq

Apio, after all, is a domestic award, presumably to take care of the contestants.

It's just a piece of AG.

Distressed Lyc,a dropped the first question but did not write the third problem of violence, AU became AG

Recordmp3 AU, you scared the baby.

Just brother or AG, say just brother Wc,ctsc,apio are AG, this is the road of PO sister, it seems Noi to AU

This apio because of the prize is very loose, so the value of some silver copper qaq feel still very magnetic ah

I talked to my seniors in the evening.

And a good relationship with the junior high school friends talk about life

I went to break my sleep.

5.9

Early morning to get up and retire to the car back to Hengshui

The car is playing very well, feel the time in Beijing is just a snap

A gold and a silver, but also to the summer camp to save some capital? (Estimates do not look

Make some preparations for the summer camp.

Yes, I should've put it down.

August, August!

Three months, three months!
