Day 0
Py school next door and the two men for a moment, a group of six teams, (left hum) and (right-hum), and I Camouflager and everlasting constitutes a right-hum.
Then fought a thupc test machine game, I do not know ye took the Introduction to this algorithm
Day 1
Playing field thupc, the money did not groan
M to open up, and then find themselves $ 7 $% forgot to positive, then no get the first drop of the first submission time: $ 0: 2: 37 $, AC Time: $ 0: five seventy-four $, +3
Then open $ B $, to get a blood not any further out of the RE Comparative autistic
This time found $ Starria $ and $ negii $ couple team got the money!
Calmly analyze it and found $ J $ is a sucker questions, to Camouflager wrote, after a while children out on A
I went to see $ F $ title, feeling a little, it is a $ K $ hex FWT, and will not find themselves, directly from your fences
This time $ everlasting $ says he wants to open the $ H $ title, and I ... and then I went and looked at C title
Sensibility to understand it, what this should be a strange combination of inclusion and exclusion + number, and then write out of, do not know where to hang up, the computer on again handed over $ everlasting $
Then find themselves inclusion and exclusion hung up, changed out change to A
Then the computer would have been $ everlasting $ there, I went and I Camouflager discuss issues of practice, thought, this thing is just to maintain the tree line just fine ah ...
Then tried to grab the computer from $ everlasting $ there, failed .jpg
Then he looked tune duck chess, write half, finally got the computer to write I, which is Camouflager write, I went to look at L
I did not find out how fast do it from your fences
After a child, I found out the problem Wa, do not know where the Gugu Gu
And then I started looking for where the cushions, the middle submitted several hair, probably from the end of the examination as well as $ 2h $
This time, it found everlasting grabbed the computer to write $ H $, after a while, yelled one, I finally the A
Quick closure list this time is almost up, I looked at the $ 6 $ a title feel should not hit the money, and then try to repair pot $ I $ title
(Who would have thought that the last reading problem, always thought it was accuracy problems
End $ 17 $-minute exam in time, left hum of people with a look of mysterious smile, said they lost $ I $ A title
Then I am very puzzled, and began to frantically change
Finally, I asked out of time, while(n--){puts("nan");}good, I'm a self-closing
The final 29, results still OK, right? Anyway, $ A $ title fairy data structures I do not really understand, EFG did not understand how, I found to be read into the wrong format, L feeling should be a very simple question, but I just do not
In addition $ Orz __ rqy $
Yulong night to begin a decadent cts life, plus and xqz and He (gao) sister meal, more autistic
Day 2
For some reason, cushions out Cts reports and test machine (thupc), so coming here today, did not know where the cafeteria and in the examination room, and then we spent time 0.5h found a canteen, canteen found it can be really difficult eat!
Then began cts Day1 exam
Send questions feel are $ \ mod 998244353 $ can be really desperate
Then shook T1 feel you can do, T2, it found $ 68 $ violence would not want a positive solution, T3, then the feeling of not quite answer the question do?
Then began to push T1, feel the problem is just $ K $ a, can be transformed into it, then I forgot binomial inversion of this thing, I think the answer is to direct $ \ ge k $ removed $ \ ge k + 1 $ of I really clever little thing
Then tune for a long time and found how also make life difficult for $ n \ ge 2 $ a situation (such as single-step inclusion-exclusion is not the result of a binomial inversion results)
And casually write off $ T2 $ violence, feeling $ n \ le 300 $ not very friendly, but not often choose cards
Then for $ T3 $, then hand-painted the first three test points to get $ 29 $ to get out, and they returned to the embrace of T1
(Cts probably think of the question answer is not very good out points?)
Then out of the examination room found that all of the basic T3 are $ 60 + $ petrochemical moment on, roll back to the hotel and then pulled into the pits bird soul, listen to Gugu Gu problem solution, and then once again lamented his mentally handicapped, open the door to squeeze his feet , and back to the hotel feeling swollen
Day 3
Feeling hopeless comeback, computational geometry + $ \ mod 998244353 $
Computational Geometry spent about $ 1h $ Da Banzai + final push nature to no avail
T2 then feeling a strange border theory, I will not, began to push $ T3 $
And then found life difficult for themselves how $ n = 15 $ of the sample until the end of the examination
