2015 about the 11th annual "Blue Fox Network Cup" Summary of the computer program design contest for undergraduates in Hunan province

------------------------------------------------------------------------ life always needs us to constantly frustrate and summarize. and move on!

Looking back at my college, I did not have a general classmate so "lucky", have a long vacation, you can do what you want to do. I choose is another road, a I have not looked at the future direction of the road, but I am a do not concede, I do not want to, their decision, because of some reasons, and easily give up!

        again this provincial race, I think compared to last year's question, today's question is relatively simple, the main test basic algorithm and thinking bar (think not, just when I did not say). Last year, a quick quiz, 3 5 6 7

this year the provincial race in Chenzhou, wow! So far, from Changsha in the past 4,5 hours of the train, sit fortunately some, unfortunately, the tickets are sold out, we are all standing back. Station 5,6 hours really tired, especially I also carsick (too long no car ...) ) to school one o'clock in the morning more. Fortunately, there is a kind aunt on the train let me sit for a while, otherwise I will stand sore leg, that acid. Here is still to say: Thank you!

It's all ripped in the front, haha!

provincial race was a little tense, after all, I was the first and last time to take part in the provincial Races (invitational not counted), Shonan College, everyone in 7 Building Competition, the first responsible teacher told a few requests, our captain began to head files or something to get it done ...

at the beginning of the game, when we got the title,ASkip the English question;Bproblem (real number than size) Chinese water problem, the captain began to adjust the code, the simulation of large numbers, I went on to see the next question, a look at another Chinese;C(The public part of the polygon), I think, geometry, point in the polygon, can do, but all are knocking the template is too slow, so positioning for the first4,5problem to do, and then look at the following questions;Dproblem, byQujieI looked at it.Equestion (Simple graph theory problem?) I handed the question to theQujie, he went on to look at the following question;F(factorial multiplication), I want to be able to do, hurriedly callQujiecome, say the next question, listened to his thoughts (N! =k*m! ,1<=k<=10^9, fixedm! DetermineN! , enumerate the smallestm! ), I'm out of my mind.,I knocked with my brother before we left .Javafactorial, big number Ah! But our team, they haven't written for a long time .Java, and there's noJDKcan check, I will give up this problem first, to see the next question, (this process is not very long, write more wordy);

GThe problem is in English, my strategy is to look at the Chinese problem, after all, English reading problems and slow, first readJquestion (another simple answer), the end of the number. Simple question Ah, hurriedly put the idea and the captain said, at this time, the captain has put a problem of code knocked over, probablyTenmin, did you ask me what test data I have? I want to say: real words, there is no analog negative, he saw no, change a judgment, measured a few groups no problem,OK, paid, but too hasty to make a point not to change the language of submission,CEonce, changed and handed over again (13minUnfortunately, when the penalty was just beginning, it was okay, and thenTenminand then putJQuestionsA, this timeQujieand theLibinTogether to discussDI'll think about it later.FI try to remember and learn to write with my brother.Javacode, and then write the code on the draft paper, half an hour later, the search question was over (in the middle of the wrong one), we brushed the next question, seeHquestion overa lot, (simulation questions).

our fourth and third questions were very long, almost one hours apart, during which I knockedJavalarge number, with mixedQujieof theEgraph theory, there are knock geometry template, but we are not correct, the reason is that, because IJavacode NULL pointer exception, I am also confused, and he is not a sample, this time by the printer printing, byLibinto knock the simulation, and then it seems that the reason for the colon, a long time to check the wrong, in killingHafter almost OnePoint, and then we're in the same school, and it's already out4problem, ranking is still in front, we are a little flustered, (pressure Alexander) I finally found their mistakes, forget the initialization function, Halo! Compile finally, measured the sample can be, I handed it! A pity.WA, took over and the captain studied the next, told me the idea, the captain said large points group, the results opened100010or is10010, re-handed, turned for a long time, timed out ... Then we think the idea is correct, and the array is smaller2001, (at first it was1001), the result is stillWAAnd then we started testing the data and later found out that besides1should outputImpossible, the others should have values, and then there I went on thinking, and they turned to writeEquestions and.

I also knocked the geometric template, but because the template and I usually write the template writing format is very different, I am too lazy to change, resulting in the completion of the template, run the sample after, printing, began to mistake, by the way let them write the topic, we had the fifth question, too late to happy, looked underRank, found in the silver of the last few, the gold also must be at least cut2other teams in the same school5) in turnLibinthink with me .Cgeometry, he had no other idea, I did not think of any pit point (except concave polygon, all inclusive, point does not contain the inclusion of edges, which I later thought), first lay down the geometry,QujieTo thinkI(the rest of the present exceptFmost of the questions), at noon lunch on our team, are not in any mood to eat, because only about 1.5 hours, our school's other teams have been out of the first6question, (the middle of the one hours, we keep debugging, but still wrong) I am also very nervous,JavaThe large number hassure is the wrong idea, because the first was brought into the wrong, comparedkMaximum has10^9, the table is in any case can not save.

and at the same time a lot of balloons were sent to our examination room, (black Horse is really many), I want to take silver at least6the problem, but also very Xuan! The one who's worried, we don't have this feeling at all.!What I thought later was the use of factors, andLibindiscussed the idea, was rejected, is not good enumeration full AH! What to do, I thought for a while, with the approximate, well, and then discuss with him, he then can see, has been very dizzy, after all, the atmosphere is so depressed, and was the same school beyond, (at that time I think, we can only take copper, not reconciled!) , he did not fully understand my train of thought, said will not time out what, I also can not control so much, I follow the thought of knocking, but the operation of the time did not result, I do not know how, then may be nervous under, incredibly put forLoop into a dead loop, ah ah ah ... ThenIIt's starting to knock, I checked.5minfinally found himself wrong place, changed a bit, and then the last half-hour time, and that the good nervous.

30min libin i I didn't have enough time to debug because of the geometry problem, and I was at the end of the 20min Just think of not the point contained in the polygon, but the line segment, I feel that I have no time to hit the code, I can not guarantee that they did not miss the other pit point, So I pinned my hopes on them, and until the last few minutes, I always believed they would be able to debug. After all, you should trust your teammates in the game, right? At the end of the teacher announced the moment, I also hold the idea, unfortunately, the last commissioning or have had. 〒_〒

finally Rank put the list, we see ourselves in the last of the silver, only loose half tone, but still very worried, after all, do not know the final results, and so on to check the weight of what, such as the closing ceremony will be announced, we have no good advice to the coach, after all, was given the expectation of gold, but can not take? That is we are still very nervous, at least I am very nervous, see they play better than us, I am a little remorse, I am responsible for the geometry did not knock out. In their laughter, our team's relative silence a little, no matter how, now is not to blame each other, but to regroup! After the photo shoot we hurried away (unfinished train) with that mood, in 4 and a half, the discussion group left to attend the closing ceremony of the students told us the position when the time to fall in the heart, sitting in the bus, we also discuss the point of the pit when the problem, Then talk about their own method of solving, we are relatively noisy behind, then I was a bit carsick. A little uncomfortable. (I think the people next to it must be annoying us) ... The next is the station train of bitterness.

Overall, we played the game is not ideal, on the one hand, the pressure is not enough, on the other hand is not enough; the next day, if you want to go to the Regional win award, we have to play a good match, adjust the state, I also want to take responsibility of the part, well organized. (If I've knocked on that template before, we have the hope of the seventh question, eh!) Other people's templates are not their own after all. ）

Guys, come on!!!

unconsciously, actually wrote the 3 more than an hour ....
