After listening to the class for a little more than an hour in the morning, I found that I didn't understand anything, so I decided to skip it.
In the afternoon...it turned off decisively, and then found that others had just finished class when they came back from dinner...embarrassing.

After skipping a day of class, I suddenly wanted to listen to a lecture in college in the afternoon (it was useless anyway).
After listening to my classmates tell me that someone said, "In his opinion, the topic is more important than me", I immediately panicked and felt cold.
Obviously I didn't do it!

The point is, I don't know what I'm doing for an hour.
Look at the first question first, hey, 50 points seems to be OK.
And then it won't work for a long time.
It's 30 minutes, and it won't work after a long time.
It's still 20 points, the tree hash is easy (I didn't realize that I didn't write it)
I was ready to write, and suddenly went to see T2 on a whim.
Hey, after looking at it, it seems that 40 points is easy. Hey, adding a line segment tree can give you a full score.
ZJOI2018 has questions that can be done...I don't believe it.
After thinking about it, hit 40 violence first and then change it.
After finishing the code, the violence began to tune, and I don't know how long it has passed.
I passed the sample easily, and I tested a large sample, and it was all wrong...what's the situation.
I looked at the data... I didn't open long long.
Change it and test again...one wrong...what's the situation.
Then I don't know how long it took to find that the special sentence was wrong when it was repeated...
Then I am ready to change the line segment tree... Suddenly I find that it is not enough to find the minimum value... It seems that I need to add something...
I looked at the time at this time... 12 o'clock exactly...
Suddenly remembered that I never played T1...
The start code is T1, which is very convenient. At first, I thought all kinds of random hashes would work...
After the first two or three samples, it's pretty normal...
Suddenly found a group of n=10, suddenly cool.
Start to change the hash randomly. Suddenly I found that the output is different every time I change the answer...
I started to measure n=5, hand-painted a hair, and finally found that I was cold...
There are ten minutes left...
The mentality is wrong... I glanced at the T3 topic and didn't read much...
I thought it was the whole point! I feel trapped, I output a 3 at random, I don't know if it will be CE...
Continue to change my hash, but failed to change it.
After the end, I suddenly felt a little bit wrong... Other people's part points are 20+20+10...
Someone 20+40+10 steadily enters the team
However I am 0+x+0, x<=40...
顿时感觉自己傻了。
还有T2 w,l<=50的那个都没怎么去想......哭
luogu+loj打卡......果然两个凶
总而言之还是那句话，考挂了自己弱。
