CCPC Hangzhou Tournament Summary

Compared to the previous game, I did not have any baggage, light, warm-up two nights before the eight o'clock bus to the railway station, traffic jams, almost missed the train, fortunately all smooth to the Hangzhou reservation of the hotel, which is already the pre-match four o'clock in the afternoon the day before, equivalent to 20 hours of drive, At night with a group of big guys in Henan school chatting (although I did not say a lot of words).
Sleep woke up already is the morning of the warm-up, and teammate Zjd&&zgp also work in Hangzhou with the school sister WH go to Hangzhou Electric report to collect the entry clothing and entry manuals and other items, and then in Hangzhou Electric Lunch, and in Hangzhou Electric turned a circle, In his spare time, he saw dogs and ducks in the lake for a 10-minute chase, followed by a warm-up.
The warm-up began, began to see the topic, inexplicably read a question, (instantly feel that they can be English four class, said ashamed, junior has not been four levels), because I am in the competition to read English topic ability is basically 0, this read the topic, and is a water problem, directly go to knock Code, memory is 1 A, And then test some things, because it is in the hduoj, so everything is very familiar, there is not too much to test things, said the warm-up do not more than a question, will lose character, so the teammates unanimously decided not to do the problem. After the end, go back to bed early to prepare for the next day's official match.
Seven O ' clock in the morning when the alarm rang, and then saw Zjd already up, and then wash, I lie down for a while, waiting for him to wash well, and then with his teammates && Learning elder sister went to Hangzhou Electric, enter after a meeting, the game began.
    Game began a few minutes later, someone a A, so that the team-mates to translate a question, then my fighting capacity of 0, do not understand test instructions I knocked the basic input and output, this is ZJD has translated, so I translated this problem, feel a little thought, try to write, Write wrote found a bit of a problem, and then discuss with teammates, then ZGP teammate pointed out zjd translation of a small loophole, missing a condition, with this condition, the topic became very simple, changed a bit 1 a. Due to the problem of the previous topic, there is a small problem in the middle of the translation, a problem is already 53 minutes. So saw the next list, found that the F-question to do more people, teammates to me to translate the topic, so we discuss the problem, I think this problem only need to enumerate the last digit number of digits, up to three, then the front can be determined, so choose to let ZJD knock this problem, I and ZGP to see the C problem, I have not read the question for a long time, the accident is ZGP also did not understand, then ZJD F problem code has been written, measured some samples, feel quite right, submitted, the unexpected is WA, and then decided to find the wrong team mate, I wrote a data, found the code can not, then debug, debugging, Found the problem, teammate Zjd in time to do a change, and then measured a few groups of samples, in this period I have carefully considered my thinking no problem, it should be the code of some small bugs, decided to cross the line, it is reasonable a, at this time is 1 hours 27 minutes, because of the C translation card, when the C question a person relatively more , two teammates are translating the C question, because before the teammates to me said inadvertently heard the next team said K is a water problem, so I translated K problem, because I translation ability is too weak, decided to think about K, two teammates have been in translation C, but next is Hangzhou electric A team Ah, strong school team mouth water problem may not be water problem, K question temporarily no idea, finally C translation has progress, analysis is a greedy, so I decided I went to knock C, after the test after the sample, the courage to submit, WA, good embarrassment, the more I think is not their own ideas where out of the bug, feel no problem, Then it may be the translation of the place missing things, read the discussion version, found that the title should be real, but still not quite sure, because the code before WA is only considered integers, repeatedly asked teammates are integers or real numbers, the decision to change to real numbers, the code needs to be modified not many, changed to real after the heart or no bottom, But after testing some samples or decided to turn, and WA, I feel good TM blue thin, WA two hair, printed the code, then let Zjd to write B, I read my Code, and ZGP discuss the code may exist problems, thinking is not the accuracy of the problem, decided to change, During this period teammate Zgp should also translated K, and gave me the idea of K, but at that time a team of few, out of confidence, I let zgp temporarily give up K,Because Lot C idea is correct, and at this time to Zjd B problem thinking found the thought of the bug, I went to change C, add some accuracy on the decision, and then measured the extreme situation, found in the data range in 1000000 when the error 1, but continue to modify also can not avoid this error, decided to cross the pitch, The dramatic a C, then already 3 hours and 43 minutes, there are one hours, then the most is the B, so decided to write B, (this may be my game a wrong decision, killing the teammate Zgp wrote K idea), because there is no idea, only think of the problem into a diagram to write, I wrote a pre-processing process, the input into the diagram of the problem, then there is no idea, I let them think first, I first violent search, to the game there are 40 minutes, teammate Zgp said may be connected to the thumbnail point, then I also have to search the above optimization, or let the teammates use the link graph template to set a pitch, So they two sets of template to go, I choose to think of my ideas there is no optimization, I think of the treatment of the point to 1 of the points are to spend, and after the discussion with the teammate Zjd, feel no error, decided not to write connected map, but also to search, and then follow the idea of writing, handed and then WA, Know that the game is over without a off.
Another CCPC the experience of the iron, last time last year's Nanyang station, the feeling of bronze at hand, unfortunately, or too weak, back to the hotel is still thinking of the problem of the B idea, and did not think, because the array of degrees forgot to initialize, so this has a problem, then I think of the addition of initialization errors, But then I think of the idea of avoiding this bug, just after the second search to determine whether the ring on the degree of 1 can be avoided, (correctness needs to be put out after the question to write a verification) after the game also thought of K-Q spacing is not too big problem, but it is already too late.
Overall, the game is not very good, the C-question takes too much time, so that the last time is not enough, and then pay more attention to the details of the problem.
