Records of gdcpc Guangdong Provincial Games in 22 years

Big two old vegetable dog , The first silver medal , Thanks to teammates Lin Ge and Chuang Ge for flying

By the way, congratulations to the whole school 5 A team of silver medals , It's so numb 233

Let's go back to the scene .

Get up at eight , Gather with your teammates and rush to the computer room , Then I found that I didn't bring the computer power cord ....

Warm up game a Look numb , The person who warms the heart , Remind us of the final exam , To review professional courses

It is probably ten judgment questions composed of some professional course knowledge , Microprogrammed controller has the advantages of high speed , What's the advantage of this kind of , Warm your heart qaq

Wrote a bc

It's 11:30 , The opening minute of the home team of Lou Jiao was wonderful b topic , Let's look at Euler numbers 、 The title is also called fft, For two minutes , Then I see the definition of the first sentence of the last request , Discovery output n! that will do .1a The second

Then follow the list d, After manual simulation , Lingo found that the backward push was a Fibonacci number , Just split it in half , Write and hand it in wa 了 , Find out n=2 Special judgment required , Changed the next 2a

After that h Pure simulation problem , Chuang Ge 1a, A steady group of

During this period, I will talk with brother Lin f The discussion came out , It is also a simulation plus set The number of maintenance tables has been x Personal occupation is enough , Brother Chuang is also the queen , Brother Lin finished writing on the computer 1a 了 , At this time 1 One and a half hours , Everything went well , Our team is here too rank10( Not including the star team ).

While brother Lin was on the plane , I discussed with brother Chuang l topic , After exchanging ideas , I thought we thought the same thing , Then brother Lin came down , I wrote a fake practice , I found that I couldn't pass , After discussing with brother Chuang , It turns out we thought differently 2333, And a new one , I wasted half an hour , It's too stupid for me qaq period , Brother Lin and brother Chuang came up with j Problem practice , It seems a little difficult to write ？

For this problem, we need to maintain the second largest value after the largest value , There are a lot of details , After writing it, I adjusted it for a long time , After adding some special judgment , Hand it in wa 了 .

At this time, brother Chuang and I are a little autistic , Brother Lin writes on the computer j, After writing for a while, brother Lin said it was a little difficult to write , By this time the time has passed 3h 了 , The last time distance a It has been an hour and a half since the problem was solved , our rank It also fell to thirty or forty （ It does not include star striking ）, At this time, our mood is a little depressed , I went to ask brother Chuang l Some details of changing the root of the question , Brother Chuang happened to see a mistake , Hand it in 2a 了

We have regained our fighting spirit , here rank Come to about twenty . After reading the list ,j The number of people who asked Yasuo is about the same as that who just asked for another root , And then there was e topic ,01 The change of matrix connected block . We all look at j,

After Chuang Ge and Lin Ge discussed the new approach , Brother Lin gets on the plane j After finish , Hand it in wa 了 ,debug After half a day, I added some details wa, At this time, it has been blocked , We rank28、29 about , To tell you the truth, I am very desperate at this time , Because I always thought j Question direct simulation + Greedy wrong , It should be dp, Haha, but I can't , Just watch e（ Don't give your teammates fake tricks , Pure actors ）. I sat for nearly half an hour , Brother Lin found out that he was greedy before , More contributions to friendly forces , The final reprocessing is optimal , Before that, it was the extra contribution each time .3a！ We were relieved , The silver should be stabilized .

There are still more than twenty minutes , We opened the door , My mouth stuttered e after , Start blowing 2333

To sum up , Find the previous question , Thinking is more important , The algorithm used is also popular . Two simulation problems are unexpected to me ... Finally, I would like to thank my teammates for flying , Come on in the second half of the year ！
