day-50：
All the members of the high school went to Beijing for training, and I was abused into an idiot (it seems that the total score is the 3rd lowest in the school).
day-20：
I'm back in Guangzhou, and the intermittent test is slightly better at 55555.....
day0
It seems a little late to wake up in the morning qwq
Then I simply hit the FFT board, then hit the kmp board, and finally looked at the principle of expanding k.
During this period, I actually typed the 2pi/h h of the FFT into n. …
In the afternoon, we gathered at the entrance of the junior high school and took the bus to Zhongshan.
Zhongshan No. 1 Middle School is in the urban area (unlike ours), and the hotel is within a 10-minute walk. Finally, there is no need to take a 15-minute bus commute like in previous years. Yes!
Good luck this year, the hotel is divided into a suite with a living room hahaha~~~ (As a result, this place has become an entertainment center~! @#￥%...&*()——)
I played chicken and jokebird at night.
day1:
Arrive at school at 7:40
Entered at 8:00, ten minutes after the test machine, I was told that the test 23333 would start at 8:30.
After reading T1, I instantly came up with the method of $O(n \times d(n))$, considering that $n≤10^6$. Then d(n) is a maximum of 240, and it took 10 minutes to write.
After finishing T1, I went to see T2 and T3. I felt that T2 should be easier to put in front than T3, so I started T2.
