ZJOI2018 Yuyao Travel Notes
The first day of ZJOI2018 Day2
Today is the first day of ZJOI Day2. In the morning, senior Chen Bohan from Xuejun Middle School gave a lecture. At the level of this konjac, I couldn't understand it at all. However, everyone in the audience didn't seem to understand. The senior asked around, but no one understood the QwQ, which made me have the urge to want Orz. One morning, my head went up in a circle, and I didn't know what QAQ I was here for, so I spent the whole morning like this.
This afternoon was a class given by Senior Sister Mao Jiayi from Xuejun Middle School. I had often heard of Senior Sister Mao Jiayi before, but today was the first time I saw it. She first came up with a water question, which I could do as best I could, and then started the second question, I couldn't understand it, woo woo woo~. Another afternoon. . .
Yuyao Middle School is quite good. First of all, there is a grand entrance, like the Arc de Triomphe. There is a road after entering. At the end of the road is a sundial standing in front of the Science and Technology Building. The Science and Technology Building seems to have six floors. We are listening on the fifth floor. class, although their lecture hall is a little smaller. Looking down from the top, the top of the corridor connecting the teaching building and the science and technology building seems to be covered with lawns. There are also several tables on it. Some students are reading books. Although the place is not big, it is very eye-catching. Featured.
However, the food in Yuyao Middle School is not very delicious. It may be because the distance is far away and the habit is different. The taste is too bland. Anyway, I don’t want to eat it again. There is something missing, and the meal fee is paid to QAQ in vain.

The second day of ZJOI2018 Day2
Today is still the same. It was already night when I wrote it. I forgot a bit, but I remembered a topic and thought it was very magical. Although I didn’t understand it, I thought the solution was very strange, so I would like to share it with you.
To the effect of the title
, there is a bipartite graph, It means that the i-th image on the left and the j-th image on the right have a length of edge, asks if you have a perfectly matched weight sum that is a multiple of K.
The main point
I always thought rand() can be used to solve [funny].
Yesterday, I went to the community college to test the machine, because Yuyao Middle School is not enough, I think the keyboard of the community college is very good, a bit like a mechanical keyboard, much better than the ordinary keyboard. I heard that the computer is much better than Yuyao Middle School, but I didn't know how bad Yuyao Middle School's computer was until I tried it [wiping sweat].
Waiting for the provincial exam tomorrow. come on! ! !
The following is a selection of topics for Day 2. Selection of
topics
The last day of ZJOI2018 Day2
Today is the provincial election exam, it's cold anyway.
Day2 test papers and solutions
After watching these two times, I wanted to retire QAQ as soon as I experienced the provincial election.
Mental explosion, this is my experience.
If I test algorithm and optimization, then my score can be higher, but what the hell are two math questions?
The second question is to send points? It seems that I am so weak.
After this provincial election, I got some, I don't know if it will help the juniors and juniors (don't look at the big guys).
The basis of the algorithm must be there, otherwise, if you quit understanding the method and find that it is not possible in time or space, then you will cry and faint in the toilet?
Mathematical skills must be strong, otherwise you will not be able to push even pushing, sitting in the examination room for 5 hours, you will feel infinite despair.
emmmm, as if these are crap.
You can score as many points as you can, and you can get on the violent meter. Don't be afraid of running out of time, there is a long time left each time.
Then there is nothing to talk about, it's all NOIP routines, just move it up.
