CCF promotional video quotes:

Suppose there are l to r, this is l, and this is r. I don't add these edges. I won’t add these edges! How to do violence? Is violence, add edges, add edges, add edges, and then, and query.

(Note: Second grade of junior high school, first WC)

I saw the notice on the official website and prepared to register. After asking for a long time, the teacher said that a questionnaire will be sent out in a few days for unified registration.

I finished urging the teacher and the registration was successful /cy.

The registration was successful and I joined the WeChat group qaq. I wish me success in getting Cu.

I entered the conference room at 15:00 in the afternoon, watched the CCF promotional video hundreds of millions of times, and also captured three pictures of the 3M principles (

I was photographed by ClCN in the group, so I I found out about ClCN’s real name (danger)

Then I told Ben Ben about it, so I don’t know how many people knew my real name (of course, they may not have noticed)

Then in a blink of an eye, I saw I went to ClCN and took pictures of He Lin (risk)

I originally thought the opening ceremony would last half an hour, but it turned out to be only 7 minutes...

I wanted to enter the first class but found that I couldn’t understand the course materials. Decisively go to the second class.

In the morning, I understood some DP models and optimization, which was good.

In the afternoon, I learned about how to cheat Q from classmates/parents. Very good!! 11

I reviewed the online class in the morning and it felt good.

I remember the teacher’s saying: we just need to finish class before the afternoon class. Did you?

Teacher Jia Bian (?) gave a lecture in the afternoon, and I understood the basic strings. I was a little confused after exKMP and SA, but I still learned something.

In the morning. I talked about tree theory, so I understood it in the first part, and then just said "just hit the board" without explaining the definitions or the board. It successfully led to the fact that I still know what I knew before, and I still don't know what I didn't know before. So, I couldn’t bear it when I heard about the division.

The first class in the afternoon was IOI+, and the second class was pj-, so I went to write about culture class without listening to anything.

I went to the first classroom for half a day to listen to the MO class & Greek class. I was too lazy to listen to the multi-threading and parallel computing class in the afternoon.

I got up at 7:30 in the morning and took another look at CCF. Notice, I found out that the exam started at 8:30 instead of 8:00, so I came to Luogu to memorize network flow, simulated annealing, and two-dimensional convex hull, but nothing was used.

< p> I read all the questions first, and finally decided to do the violence in the order of T2→T3→T1. T2 and T3 were directly violent, and T1 was not smooth at all. I adjusted it for a long time and made a metaphysical method, but it kept hacking. It didn’t work (maybe it was because my hand calculation was too troublesome and the results were too small), so I gave up in the end.

There is nothing to describe the specific process of the online competition, so here is a picture:

Finally, I talked to my classmates about the score estimates and found that we seemed to be about the same. This is my rubbish score estimate:

I don’t know if I have failed, I hope I can get a qaq.

Then I listened to the topic in the afternoon and said that the idea of ????T1 is to add, add, add, and search the set. The CCF promotional video leaked the question and suggested banning three! ! ! 11

After listening to the others, it turns out that I am still too good at it.

The first time I finished NOIWC, I will wait until the results are announced (

The score line is 70/118/158, the blacksmithing festival (((although I don’t know how many I have yet)

< p> upd: , won the bronze medal awa

Let me complain, why is the score line this year so much higher than last year/kel
