CSP2019-S travels
Day -2（UPDATE：2019-11-14）
Finished, I wrote a travel,It is not to be suspended for。
Not necessarily have just finished writing Travels, and then began to write, she felt her face really / cy fast.
After (11,12,13 \) \ consecutive days of mid-term destruction (formerly Dean said no test, and then a non-innovative classes to test English language and the number of selected test subjects, but fortunately technology do not test, or to test \ (6 \) door more autistic), people want no more.
Autistic morning exam, the hope of tomorrow "confidence game" really is a game of confidence(Accidentally became autistic match)
I began to write book, look forward to seeing tomorrow Mrsrz (after all, to the \ (\ mathrm {zhzx} \ ) semester and more, in addition to a try once met, never seen the other).
This should be the second time I travel writing, I do not know a few days later we will not continue to write(See the extent of the diaphragm splash splash behind me)Estimated to be the last time a serious game, ready to go back behind the cultural lesson, so that should also be the last time travel writing.
After high school information to learn the state has been to get up, see the topic simply could not think of a method, not last year \ (\ mathrm {NOIP} \ ) when the state is good, it is estimated that good results yet. I hope this year \ (\ mathrm {CSP} \ ) can \ (rp ++ \) , at least do not make big mistakes. As \ (16, 17 \) examination of Endeavor.
After a reminder, suddenly found that I wrote CSP2019-J, / jk, then quickly changed over (must be because I was too dishes), but fortunately I did was wrong at the time of enrollment
\ (\ mathrm {FSB} \ ) to mobilize room classic statement:
- \ (\ mathrm {dp} \ ) Template see more
- Chinese variable Natori point
- To look at the subject out of the topic, the topic from a human perspective, any problems have flaws
- Each of you is less than \ (400 \) points, just shoot each of the offerings, with a clear conscience is good.
I: \ (\ mathrm {FSB} \) , I got \ (0 \) points, that's my level, I shot each of the offerings, with a clear conscience
Day -1（UPDATE：2019-11-15）
I am confident game:
In recent years, the feeling is one of the most conscientious, you can finally get a normal \ (300 \) points it! Finally it is not self-closing race!
\ (\ texttt {T1} \ ) the simplest and the end of the longest code is found. . . The next two questions short code is good ah! \ (\ texttt {T3} \ ) was originally used to practice our tree \ (\ mathrm {DP} \ ) , and not many people write \ (\ mathrm {DP} \ ) , all written conclusions go.
Today so smoothly, the next two days is estimated to be cool.
In the car that Jiaochuan out some wonderful things, and may not \ (Mrsrz \) live together. Start all kinds of panic, panic themselves "homeless." To the hotel, at the door waiting for \ (20 \ texttt {min} + \) , then you can listen to the teacher and said, \ (Mrsrz \) to live together, and instantly feel better.
Our room \ (21 \) floor, the room is directly opposite the almost direct access to the first floor of a thing. Afraid of tomorrow autistic accidentally go.
And \ (daklqw, Weng \ _weijie, Mrsrz, YuHaoXiang \) for dinner around the hotel set up numerous laps, and finally by \ (daklqw \) finalized find a hot pot shop, eat actually very full.
Evening \ (8:45 \) (that is, I write this sentence) has not yet begun to see the template, tomorrow Huang Huang panic. It would look refueling.
Today too little decadent, it is estimated that last exam should seriously spot.
I wish I could have a good result tomorrow!
Day 1（UPDATE：2019-11-16）
Today is the first day of the exam. Last night there were no splash diaphragm, should be out of the game for the first time since I was not throwing the diaphragm at night, slept very good.
Breakfast is actually in the canteen? ? ? ? Actually only one arrived \ (10 \) dollar bill? ? ? Serious negative feedback. Laid-day basis autistic.
Wenyuan to the high school, the toilet is bad review, test sites in the underground garage, generally like it.
Start of the game, the password is Ren2Zhen0Si1Kao9why this year is so serious.
Opening first with \ (\ mathrm {vim} \) , Huh? Why not change the font? Why do show Courier_New中包含1(can not remember exactly)? Changed \ (10 \ texttt min {} + \) , forget forget, not changed, it will default. . . (After examination found that I wrote se guifont=Courier\_New:14, it should be se guifont=Courier\_New:h14). Attractive really bad \ (\ mathrm {vim} \ ) configuration is wrong.
See \ (\ texttt {Tl} \) , Gray code, look. Ah, simply, to write for a while and then write hung up, and then found a place was wrong to hand tune it, you should pass by.
Followed by \ (\ texttt {T2} \) , it seems a bit can not write, write first read it. See the \ (\ texttt {T3} \) , seems to be the way to write, or at least \ (60 \) points should be able to take ( \ (Flag \) ). Suddenly found that this problem is a multi-test, remember the car yesterday, someone said: " \ (\ mathrm {CSP} \) ! Never measured how" immediately hit the face today.
Eh? I really want to \ (\ texttt {T2} \ ) would be a? It seems to take a look at the front of the stack to save right parenthesis, then \ (\ mathrm {the DFS} \) , for each point statistics about the number of legal strings to this point at the end of the prefix and just fine. It took less than half an hour to go back to \ (\ texttt {T2} \ ) wrote. Ok? Large sample \ (\ texttt {RE} \ ) up? A look \ (\ mathrm {vim} \ ) configuration, I opened stack written --static? ? ? How misconfigured so much. .
Did not get that done too large a sample configuration discovery, tune a tune found a right parenthesis seems more than a plus, changed a bit over a large sample I put aside.
Looks kinda plenty of time, do this year \ (Day \; 1 \) and about the same difficulty last year? Not everyone \ (300 \) , right? Start writing \ (\ texttt {T3} \) , write write write \ (30 \ texttt min {} + \) . I finished! A test data, all burst. Suddenly feeling \ (\ texttt {T2} \ ) a little nervous, time enough to look like, go back and write to beat. A beat, \ (n-500 = \) of a data of one shot \ (\ texttt {WA} \) . How so many mistakes, I will not write the hang of it violent? Looked, it did not seem a problem? ? ? Run a small data Shoumo a bit, eh eh hung up my program! Quickly tune, plus the elements found in the stack when the value of the write hung up. Tune out. Ok? Also how pot? Then I discovered the change when they added a pot. sweat.
Then beat on it (I do not know in the end is not over)! Went to a \ (\ texttt {Tl} \) , the output of the \ (n = 5 \) data looked no problem. Time to \ (10:30 \) . Hurry back tone \ (\ texttt {T3} \) , today most unfortunate thing happened. \ (11:00 \) , because in front of me to open the program stack is \ (10 ^ 9 \) . Then I did a memory? ? ? Probably like every third compilation can be successful only once? (Memory gone? Must be because too hot today 1 ). Just a little nervous. To the \ (11:50 \) or so, I can not completely compiled. Today feels they have to satisfy his hunger, the mentality of the explosion, reflect for a moment to the invigilator, let me restart, completely no time to write violence, \ (\ texttt {T3} \) burst zero, and finally apply for an extension of \ (5 \ texttt { } min \) , then do not.
Expected \ (100 + 100 + 0 = 200 \) , I do not know is not hung up.
They found that the vast majority of people \ (\ texttt {T3} \ ) are playing \ (10 \) points violence, nor is pulled too much, but it is certainly less than most people's score. Heart a little collapse, came out of the bag just finished, I did not take.
Noon yesterday and people for dinner, and afternoon \ (Mrsrz \) and \ (Weng \ _weijie \) to play with \ (\ mathrm Minecraft} {\) (in fact, a little bit not want to play), behind the mentality of good points. Still the same people out to dinner at night. Upon his return, \ (8:15 \) should \ (Mrsrz \) requirements, soak a bowl of instant noodles, eat and write this travelogue. I actually wrote a \ ({1 H} \ texttt \) ? During the \ (Mrsrz \) anger \ (D \) several times, "Hello no ah? How to write so Mana?"
I hope to play well tomorrow than today, refueling
Day 2（UPDATE：2019-11-17）
The next day, go directly to the exam today, the whole thing in the morning check-out.
To the examination room, last night did not see what information is feeling a little nervous? The password is @zhuajin1SHIJIAN7, it seems today, lack of time (laughs)? Fight \ (\ mathrm {vim} \ ) configuration, this is not a problem, but fear memory is not enough, there is no handwriting open stacks, going to encounter problems manually call again.
Open title, \ (\ texttt {Tl} \) looks OK? Careful thought does not seem to be able to write, looked under the scope of data complexity guess \ (O (the n-2M ^) \) . Then go to \ (\ texttt {T2} \) , inexplicable violence feel like good writing looks like ( \ (Flag \) )? Then go to \ (\ texttt {T3} \) , this violence can certainly write, \ (55 \ texttt {PTS} \) should be stable, they put a put, think about \ (\ texttt {T1} \) .
Probably \ (9:30 \) , I still did not score a little nervous. Suddenly \ (\ texttt {T1} \ ) have an idea, just to obtain a number satisfying the condition of the program, some of which does not satisfy the condition II is determined by subtracting. Up to know only one dish more than half, more than half of enumeration which grow vegetables, make a backpack. Wrote a \ (O (n ^ 2m) \) , and finished a test sample, I found the time to write the backpack did not take into account a total of a few dishes, and had added a one cycle. For each vegetables, do Total \ (I \) dish, where \ (J \) species are several such dishes embodiment, complexity \ (O (n-3M ^) \) , can get \ (84 \ texttt {pts} \ ) fraction. Think back not optimized, it stood up.
This time around \ (10:10 \) , and quickly hit a \ (\ texttt {T3} \ ) violence, took \ (55 \ texttt {PTS} \) . \ (10:30 \) , see \ (\ texttt T2} {\) , write false two algorithms, and then forward from the viewpoint of the feeling, take the shortest possible segment seems to be as a piece, and then continue to write, complexity \ (O (the n-^ 3) \) , the sample - 12 has been finished, the heart is still a little excited, and then sample three hung up. Already \ (11:20 \) , and quickly wrote a \ (O (2 ^ n) \) violence, took a small data set, and then I found in the back part of the judgment sometime on whether to become a problem, but I will not write down from your fences.
Probably \ (84 + 12 + 55 = 151 \) . Suddenly remembered the exam out \ (\ texttt {T2} \ ) should open a large range of violence, so that if there is data gradient can get a little more than points, but the examination is over.
After the examination room and found everyone \ (230+ \) . He retired. The \ (\ mathrm {CSP} \ ) preparation is not very adequate, there is no good state last year, it is estimated that prior to departure This is the last time I participated in a serious contest information, and tomorrow should participate in the competition is just not ready. Now the real results on the front, a little sad, after all, is to start from the fifth grade science, students and individual relations are particularly good; but I also know I can not keep going down this road, no need to worry about the future information or culture should learn lessons, and also be a way for me to indicate it. It still will miss the race time and students learning together, they wish they can get satisfactory results.
\ (skip2004 \) seems \ (AK \) a \ (\ mathrm {CSP} \) ? Invincible ah.
Under student asked, \ (\ texttt {Tl} \) only needs to be changed for each of the vegetables, the recording track number of tracks the number of such dishes can be subtracted to another dish \ (O (n ^ 2m) \) a. \ (\ texttt {T2} \ ) most people write \ (O (n ^ 2) \) a \ (\ mathrm the DP} {\) , \ (\ texttt {T3} \) to write a segment tree merge. \ (\ texttt {T2}, \ texttt {T3} \) I did not go to get to know, after all, not a thing to learn information.
Think about this one game, I feel I have not done anything, nor how the membrane splash, informatics there is no score. To back up cultural lesson.
This should be my last travel and information science association, and to finish this travel will stay focused on the cultural lesson. It should only be seen when I was elective, and perhaps write a little problem, the blog may also send some solution to a problem, but certainly not a complete dedication. \ (\ mathrm {AFO} \ ) it!
In a minute after this travel may also update the look, but after all what happened ......
My name: \ (Memory \; of \; Winter \) , are students dubbed the "winter of Memory", as long as it is winter, I had endless memory, laughing ↩
