Day 0
As a third-year small konjac ......
What the algorithm will not play ......
Do a LCA + spanning tree diagram topic tone for two hours ......
Tomorrow Hadakako ......
Day 1 Morning
I bought two Snickers with a carton of milk, ready to eat in the examination room (the word seems very strange) ......
In the car shaking, some traffic jams, but still arrived on time ......
And then on the opening test of the ......
Then I lost password wrong dozens of times ......
"Think seriously"? But I could not even question mark at the end of the sentence have destroyed dozens ......
I'm still curious as to why so many times to lose the password ......
And then I looked at the problem ......
Ah first question will not look ......
The second question does not seem to ah ......
Ah third question does not seem to ......
One day two kinds of trees, CCF is really busy and feel uncomfortable ......
Indeed the money, began his career in the environmental protection ......
Well, then the question still to do ......
Hit a 50-point analog first question ......
And then began to find the law ......
Binary conversion to decimal ......
Like the left and right side of the large side of the small (though see subject description has been able to see it but I did not see it) ......
That probably half?
So I hit a half hour ......
Two half ......
According to the position according to one-half the value of one ...... ...... ...... value even reverse
I did not write the last two ull fifth put together ......
Then look at the second question ......
Yesterday did a multiplier looks like ...... ah ......
Try multiplying that?
Confidently beat half the value of finding a solution can not be split up and the increased consolidation range ......
Messing around for a long time simply did not do it ......
Spot autistic ......
The third question ......
Ok……
The third question ......
Points will not lie to cheat ......
The second question had no time to fool you ......
Cold cold ......

Day 1 Afternoon
With room bigwigs second question has divided ......
Konjac has been afraid to speak ......
Morning force taxi stand not finished ......
Bring into the exam ......
Then what strange stuff?
You can not find a seat?
Pull 20 minutes?
The teacher also wrong password?
Also wrong twice?
……
I looked at the problem ......
The first question, as always, water ......
getchar direct cumulative ......
The second question seems simulation can also be too ......
Also you can live ......
How large a sample you have not seen?
How to 1.4s?
Unscientific ah ......
O (tn) (t <= 45) had also not how?
So I started to switch to the list ......
Fast is fast ...... it is wrong ......
The original head pointer is deleted out of the question ......
Hey, no problem, but how is it so slow?
2+s？
……
So back to violence simulation ......
Check for half an hour -
Hit if conditions go, and should hit for in the ......
At this time has passed more than an hour ......
Look at the third question ......
How is this strange dynamic programming ......
Well……
Only a minute wait a minute ...... cheat
I began to see the mentality of the explosion fourth question ......
Ok……
Diffusion from one point to the surrounding ......
Seeking to satisfy the diffusion node 1 down to 0 just when ......
Single-source shortest?
Whether seeking the shortest length L?
So the water?
Always feel quite right ......
Look at the title ......
The original transfer can be a continuous loop between the two nodes when passing ......
That changed shortest <= L?
……
Whatever the outcome is the fourth question, it would not be so water (although last year really water) ......
To pass back ...... etc ...... it means that the number is even pass each other ......
L is an odd number that seems to not work?
L ...... not seem to decide whether more than one feasible way ......
……
Shortest two? An odd one even-numbered?
So I hit it twice again for the shortest shortest ...... ...... ...... parity again points
It seemed too large a sample!
Perfect！
So I go back and look at the third question ......
Read for half an hour ......
Think-half but looked a long time ...... not think check the policy could not simply push the state transition equation ......
At this time less than 40min ......
I had to play part of the sub ......
So hit the stop test ......
Only played 25 minutes of sub-section (originally wanted to play 70 ......) ......
And cold ......
This life no chance of AK CSP-J ......
Out of the examination room ......
Gangster with a room still taller than me ......
