Into the pit ACM more than half a year, from the beginning of the a+b, to now, Mengmengdongdong to participate in the provincial race ... Although the results are not particularly good, but hope that they can stick to it, Ken pay not necessarily have a harvest, but do not pay will certainly no harvest! And I also like ACM, at least not tired!!!
This year's 14th provincial race in the middle of the big start, looking at the next door and before and after the brigade, the pressure is huge, sure enough they a 7 questions, infinite worship ~~
First start 9 point is a warm-up, pit dad's Codeblock said can't find the compiler, and then forced himself to find a network to download, finish those 7788, because the computer too card, almost 9:30, and then see the warm-up problem, I went to knock good head file and set good codeblock, they read the question, After the discussion, I found that I would not do it, and there were 12min to start the formal game, I said I rested, they thought. Then there are 4min when Zhou Weining thought, I told him not to knock, build a good project, (although he continued to knock half!!!) ) so hot save 0 questions. In the meantime I made a pitch, just want to try will not compile errors and so on, lest the official race WA.
Then the game began, a question began to understand, the English letter is too unfamiliar, and then according to the Convention, I and Wei Ning is to see a, Unzihau see the last question. Suddenly Zi Hao said that K is a regular problem, is to give f[0]=a,f[1]=b,f[n]=f[n-1]xorf[n-2], give a A, a, b f[n]. Obviously there are regular, Wei Ning thought down to knock, I take the dictionary to see a, Azusa Hao continue to see other questions, 8 minutes after the K 1Y, The excitement, the beginning was smooth. Then I told the meaning of Wei Ning A, is to give a four-sided shape of the length of the 4 edges and the length of its diagonal, asked if it has no circumscribed circle, just to determine whether the diagonal addition is 180 degrees OK, with the cosine theorem, (although I initially thought if the rectangle, in fact, I was heard in the group this discussion, but was defeated , is it in deceptive?), Wei Ning to knock, I and Zi Hao discussion b. Not long after the sample was submitted, WA. Then it thought it was not accurate enough to change into
1e-10, he would like to pay and feel that can not be, and then I encourage it to pay it, WA more than once there is no so-called (in fact, I do not agree, Precision 1e-6 absolute enough). So it's WA once more. Then I said I'll do B, you print the code out to adjust the bug it. Saying that printing is really fast, 30s is not enough to send. B is a question of construction, ask you: Give an n-point of the graph, require each node variable must be 3, ask whether it is possible, there will be output matching situation, this problem manual simulation is not difficult, you can find the point is odd time must no, even is very simple. Knock Halfway, Wei Ning said I pit, explain a problem is not clear, the figure is wrong, the corresponding input edge error. There was no language at that time ~ ~ ~ He said I should change first, hand it up, a. The wa2 of the end of the time AH. I didn't think he was a figure that didn't understand me. Then I immediately made B, and soon I was 1 y. 48min after 3 questions, then the rankings are good. Then almost 1 hours also no problem, in the meantime Wei Ning to do the C problem to pre-processing factorial to 1e9 did not have to do, after the game found to use a Polya theorem? Anyway, I don't understand it now! Then Azusa Hao called us with the list, said I is a simulation problem, translation Morse code, I said the simulation problem I come. Then I looked at the question of about 30min to understand what it means, go up to knock, violent simulation, the problem of simulation to deal with more details, when it was called Wei Ning in the side to look at, and watched for a while, I found he did not see. Pit AH ~ ~ Then I myself a person knocks, over the example, he gave a set of data, passed, turned up, incredibly 1Y, this problem really did not think, to deal with the details is too much, it is easy to more than one character less one character, I am holding WA's mentality to pay. At this time 4 question is our freshman rank1, very excited. Then I and Ning God discussed F, said that there are n people, they have a[i] yuan, to make them have the same amount of money, can pass through the bank, charge the fee k% yuan. Ask at most how much money they can have. At the beginning of the question did not understand, collect fees, if I give you x yuan, then I have to pay (1+k) x yuan is not it? And then found that the sample is not too. Later found that I give you x yuan, the bank in the X-yuan buckle k*x, so I give the person can only get (1-k) *x yuan, pit ah, that there is such a fee AH ~~ and then read the sample, or no idea, and then Zi Hao said a very important word, two points answer! Yes, I instantly think of how to write a judgment function, go to knock, where the Azusa said here all day to write the wrong, there is not, said I dare not write, change Wei Ning write, 1Y, in fact, and my ideas like ah, why not write to me ah. ~ ~ ~. Then 5 end, in our freshman ranked first, a good result. After a lot of brush questions, many points to progress, this should be the bronze bar, Pai 90+ name. ~~~~~
