NOI 2019 Travels
Day 0
Written, seemingly not even seat restrictions, and it really does not prevent open black? ?
But anyway, get points, it also does not matter, be happy.
See test machine interactive game have questions, it seems to understand what ......
Day 1
One can see there is no interaction, rest assured that many, opening look at this \ (T1 \) , it really is a sign according to the traditional title, spent \ (1.5h \) over a large sample.
The \ (t2 \) court misread the question, and that every step must meet the requirements of two adjacent partial order, then launched a monotonic continuous period of no longer than \ (4 \) strange conclusion, write out of anger had not found \ (the sample2 \) , written out of my own code violence found no problem, then find misread the title, but only \ (2h \) , and ponder for a moment you can find a similar maintenance division something segments and then merge functions, but find it hard to write and nothing superfluous (50pts \) \ good writing violent, so determined to write a \ (50pts \) violence leave.
\ (1h \) to see \ (T3 \) , first \ (36pts \) violence written, then guess conclusion, then ran third sample \ (diff \) , I found that over, feeling the steady .
The results showed that last question only \ (20pts \) , carefully check the field looks like I \ (diff \) to obtain a second sample, zbl ...
I heard the captain BJ EI only 200 did not feel this year \ (dls \) up the scene may be fishing a lot more than last year ...
Even so I \ (100 + 50 + 20 \) substantially \ (BJ \) can be considered to satisfy his hunger.
Day2
Feeling \ (day1 \) probability scores into the team is unlikely, so the attitude is also flat a lot, the first question scrawl a \ (KDtree \) simulation \ (DJ \) , the results of this writing is three hours .
Know that cold out I gave up looks extremely can do \ (t3 \) instead began pondering \ (t2 \) approach, excitedly introduced a form of convolution, found that simply does not exist in this part of the sub ... ...
Fifteen minutes left to do \ (T3 \) , had a scrawl how many points I do not know what to pay.
Then only \ (80 + 40 + 8 \) card line \ (Ag \) roll thick, a high \ (OI \) will stop here.
Day3
To the day of departure, although this result is not ideal, but I did not lose too much confidence. Many of her sophomore partner in his side's defeat in the race, no alternative but to retire, but also feel sorry for them. A high this year, let me see the \ (OI \) hard this road, people can come to the end they are worthy of respect. Those who wish to say goodbye \ (OI \) stage of seniors realize their dreams in their hearts, but also want to not forget the early heart, firm belief in (OI \) \ on the road to take a good following every step.
