This soy sauce note was posted on a classmate's blog called code-hub the year before (has collapsed), so let's repost it now. . .
GDOI2016 nonsense (exploding zero)
Hello everyone, I'm DCDCBigBig. I took the GDOI exam with a group of divine cows during May Day (I feel so empty), so I'm here to talk nonsense.
Let me introduce the god cows who went together: MYH, LZY, DCX, Micheal, HJW, LZX, and LW. (They are all divine cows, so imaginary)
Day -2
Chinese && English midterm exam. . .
Day -1
Mathematics midterm exam. . . After passing the exam, Yungap Corruption 5h+
Day 0
In the morning, I went to Spring Tour (what the hell), and went to Guangyi to see some strange things (the specimen room was full of formalin flavor). . . . . .
Take DCX dad's car to Sihui.
Come to the fourth session. Surprise! ! ! There is no commissary in the whole hotel! No commissary! No commissary! hotel. . . . . . Passable. . .
Anyway, this time I came here for the purpose of breaking zero and I didn’t plan to win the prize, so I don’t need to ask so much~~ (mentally handicapped children are more happy)
The venue of the game is in the high school department of Sihui Middle School. After dinner, go back to the hotel to continue the Three Kingdoms Kill + COC + CR + watch the big event of the rampage + under the dome (there are too many activities), and then go to sleep.
The mobile phone and computer were confiscated and kept by DCX mother , so sad QAQ
Day 1
In the morning, MYH and LZY said that there were mosquitoes in the hotel, and they didn't sleep well all night (sweaty), but fortunately we didn't.
The atmosphere on the bus to school is very dull. I don't know if I'm nervous or I haven't slept well?
Come to the engine room. Shocked again. This computer room is worse than the fifth floor! Super bad reviews for chairs and benches (butt hurts to death). Halfway through the test, the drawer fell out. . . . . .
In other words, "GDOI2016 Precautions" is written as "GDKOI2015 Precautions"

I want to cry. . .
topic this time. . . . . .
T1: Math questions for middle school students! ! !
T2: longest common string
T3: An interesting level
T4: Crazy Zoo. . .
Make up your own brain for GDKOI Day2 T4 elementary school students' math problems. . . . . .
The math problems of elementary school students are so perverted, middle school students. . . . . . look down decisively
The longest public string, I don't want to do it when I see the title.
An interesting level: the protagonist is -- QT! ! ! Just after watching a Thai drama, you are on a treasure hunt again? !
Crazy Zoo. . . . . . The subject is crazy. . . . . .
The topic is really poisonous! ! !
In the end, I found that it was still possible for middle school students to do math problems to push formulas.
2h has passed. . . . . .
TMD has no clue! ! !
Decided to cheat points + play meter. After finishing the table of P1, P2 and P3, I found that there is still 1.5h
FPC Star Wars Dafa is good.
The expected score is 0+0+0+0=0! ! ! Zero preparation
After dinner, the six people will kill the Three Kingdoms together. LW loyal minister actually killed the LZX lord!
Comments, this classroom looks like the classroom of GDKOI CUHK. . .
The person who asked the question came to blow water. . . Sure enough, the person who asked the first question was the one who asked the elementary school math questions. He said that in order to solve such a "big water problem", he also turned over the syllabus of the nine-year compulsory education junior high school, and discovered a linear function and a quadratic equation in one variable, which is required for the senior high school entrance examination, and then. . . . . .
The audience responded with warm applause.
T2, T3: I don't understand at all, I'm confused
T4: Actually, this question (supposedly) started out very watery, and you can pass it directly with DFS. But in order to prevent AK, the questioner added some strange things to test our level. Specifically: tree chain division + segment tree + persistence + forced online (version tree) + language ability! ! !
The audience applauded again.
It is said that other questioners were stunned when they saw the title.
Final result: 0+10+0+0=10! !
Eh, wait, I got 10 points for Mao's second question, but nothing else? SMG
However, there is still no explosion (very comforting).
MYH God 70, DCX30, LZX20, others are 10 or 0 (really difficult).
Corruption continued at night. . . . . .
Oh, by the way, something big happened: Teacher Chen drank red and screamed! ! !
That's right, it's the same thing as shit in the legend! ! !
Here's the thing: In the evening, Mr. Chen and the seniors of the second year of junior high school had a meeting, and they negotiated and discussed the exact date to return to Guangzhou. The second year of junior high school kept saying that it was the third day. Mr. Chen disagreed. After the dispute was discussed for a long time, ylm said: "Director Chen, you drink." One bite of this and we'll go back on the 2nd. Teacher Chen thought it was poisonous (it seemed to be true), so he let all the second year students take a sip (really courageous), and then took a sip. (The picture is too beautiful, make up your own brain)
Afterwards, Mr. Chen said that the poison of this thing is chronic. If we don't see him on the 3rd, we must remember: XFZ, it's the murderer! ! ! (Uh-huh)
Day 2
I forgot to set an alarm today, got up late and rushed to the computer room.
I saw Pharaoh on the road. Is this the rhythm of dying?
Unzip password: BuyaoShuaiguo~~ (indicates that I don’t understand)
Let's take a look at the topic: T1: SigemaGo (I don't know why I thought of AlphaGo)
This question is pure SPFA with some strange restrictions, it's very doable.
T2: The question of Forest House is
actually inspired by a game. You can do a violent search.
T3:
The question of the confidential line is too long to be understood. . .
T4: The file name of the aircraft (feigay.cpp) is illuminated. . . Said to be completely incomprehensible
I made up my mind yesterday that I can't gravwar anymore, so let's type the code (hh)
The first question was SPFA and strange greed. It only took 15 minutes. After trying a few data by hand, all the data were correct, so I just let it go.
The second question directly violent DFS, halfway through and found that it is not working at all, and began to think about life for five minutes. Finally decided to go to the third question.
After reading the third question for another ten minutes, he said that he still did not understand, and continued to think about life. . . . . . MDZZ I don't seem to have any questions to do
I started to flip through the questions boringly, and suddenly saw a sentence in the fourth question: Most of the data in this question is random! ! !
random data? ! ! Immediately look at the topic, and there is actually an output of "NO"! Immediately hit the watch (unmotivated)
After being complacent for a long time, I found a problem when I went to the first question again! Instantly tense down, adjusted for half an hour and finally recovered.
The last half hour was boring, so I turned the topic again. Wait, I seem to understand the third question! Each point SPFA once and then be weirdly greedy! Instantly entered the question-taking mode, took 20 minutes to write it out, and adjusted it again.
Expected score: 40+0+20? +20? 80 in total? wow so high
good mood 2333
During the meal, MYH and XFZ said that the first question is a positive solution layered diagram, the second question is violently searched and pruned, the third question is divided and conquered, and the fourth question is heiheihei
Surprised, do you want to hang up?
Noon MC (mac version is so good) + Three Kingdoms kill
The three o'clock commentary started on time.
P1 really is a layered map, it's over, the world is dark.
At the beginning of P2, a god ran up and said a word: violent search, and then came down, the teacher said: Well, that's right.
WTFWTFWTFWTFWTF
This question is really a search welfare question, violent search = 20, violent search + connectivity pruning = 50, violent search + dual connectivity pruning = 100! ! ! I didn't even write it, I'm confused
P3 points divide and conquer. Indicates that my approach was overturned in the first place QAQ
P4 is very interesting. At the beginning, the person who asked the question asked us who didn't directly hit "NO", very few!
Then the teacher said that it seems that only these people have the hope of scoring!
The whole person instantly petrified. The audience responded with warm applause! ! !
Final result: 10+0+0+0=10. Questioned again.
LZY hit zero again, with a total of zero points (so miserable)
MYH God 120 (666666), it is said that there is hope of entering Day3 (total 190 points), waiting for the result
HJW actually got AC on the first question with 110 points, which is even higher than DCX!
Sure enough, with only 20 points, I rolled back to Guangzhou early in the evening. It is said that MYH is very poor to enter Day3, GDOI is really not bragging (enter GDSOI in the first day of the new year? Don't think about it)
Postscript
This time I went to the shou competition (nue) to see the real powerhouses and the real gods. I deeply felt the meaning of the sentence "OI is as deep as the sea", and I must work hard in the future!
