Day0

This exam is in South Polytechnic.

Go to the exam room at 17:00

Have Windows positive

Knocked on the NTT board and found out it was wrong.

On the way home, I found the mistake of hitting 998244353 in 998242353.

I was looking for a tree in the evening. Practiced hand had thought that 10 minutes would fix the result, just one night.

Finally found that the LCA was wrong.

This can also be wrong. jpg

Laying the groundwork for the Day1 explosion

Day1

See T1 first.

Isn't that a one-eyed question? Contour Dynamic Programming (SKYLINEDP) How can I write my name wrong?

After writing it, I found no sample.

It's been tuned, and then there's been no bulk case.

I was born with a strange wrong idea and wrongly proved that the transfer was wrong

That's what I was thinking.

N 3 m 2

A:

1 2

4 8

16 32

B:

0 0

0 0

0 0

Then

**

*

is 3

*

*

*

is 17

**

*

*

is 5

So it's impossible to transfer.

I went to see T2 again.

Isn't that a one-eyed question?

Greedy + line Tree

Like to add EPS?

T3

A feeling you can't do?

First 25 minutes of violence.

And then back to just T1.

And then just to the end of the exam

Still no bulk case.

Gg

I felt it was (60-100+100+25)

Eat at noon.

A volunteer took me and zyj away.

Found gone a long time back to the halfway through a point and the rally?

？？？

Black question mark. jpg

After the big Army DFS, we found the cafeteria.

There was a lecture in the afternoon, but when we arrived, we were informed that the lecture was canceled and everyone was free to watch February blue.

It's too late to go home. 8 of us kicked the water bottle on the basketball court.

7:2 I'm in 5.

Then 3:30 to the computer room to see the score 30+20+10=60???????

How did it explode into this?

YJZ300 vigorously AK

csl280

zyf250

dy215

djq200

wyf185

I'm 60???

4:30 Listening Questions

T1 I first wrote the positive solution.

T2 I don't know if it's 60 false greed or 100 positive solution, but not 20? Maybe I got a big EPS?

How can t3 violence have a wrong call? I do not know the wrong is the chairman of the tree findkth or pressure? Seems unlikely to be wrong?

Anyway, the day1 is heavy, Day2 's not moving.

Luckily it's an informal player (because Noip 6ce weird 0)

Day2

"It hasn't started yet."
