[Exam reflection] 0803NOIP simulation tests 12: repayment

Ah, rank5. Nothing can be evaluated, the level is not too high not too low.

A good question, I was wasted.

God sent from above large 280 bit far.

Sub-room vanish coming.

Become more and feel dishes, the overall level of competence in decline.

Said that not only the examination, including the usual.

The bar exam, T1 is a math class, it is simple to find the law, A out. I did not find the law of violence have 70 points.

I do not know why, so do starkly simple question. Overall a total of 14 AC it shows the difficulty really is not high.

Although it kills it, but time after two serious pressure on the problem.

Simple question cut to cut, cut can not afford to violence, to use the shortest possible time to get as many points.

T2 normal idea is advanced data structures, thought a moment and do not know what to segment tree maintenance.

So due to time constraints, did not think, I played a little optimized Mo team, kinda high 70 points, and when Cheng was reviewed.

However, positive solution is actually very simple, is to find the law by observing the meaning of the questions, then left with a call STL, 642B can be AC

Simplification of questions intended to observe the nature of the topics included, allowing the problem is greatly simplified.

T3 part of a lot of points, but not very good to take.

First, for k = 40 points 1, I have a backwards greedy idea, but not sure of its correctness (the time is not sufficient), did not dare -40

Then hit another low violence wrong. K = 1 leads to all lost.

The last breakpoint cnt-1 times continuously output. I. . .

Reverse this idea is very important! This greedy train of thought is very important!

The examination room does not have to resort to what should prove it, time does not permit, score the most important!

Test Points partition cheated 12 points.

However, because I disjoint-set topics loopholes, this question no clue. eye for eye.

He took an afternoon supplement disjoint-set topics (in fact, also 40 minutes) and then the whole rest of the time T3 in liver liver out.

However, up to now we have not changed it. Too rubbish to death.

They really seem to have become weaker, in addition to examination by violence and with a ranking cheat Gou points, after the change usually do question test questions are slow and poor.

Now it seems more and more to understand the coach's "curse": now the top two rankings is often not able to go to the end of

Why "curse" word quotation marks? Because it's too real.

I think that the basis of the difference between slow brain can not keep people left behind, should be a matter of time.

You do not have that strength, you stay in such a high ranking, it only shows, others being just too lazy than you.

Hopefully skyh can break the curse it. I curse in death.

Do not say, T3 continues to change it.

 

Changed from 8/3 to 8/4 15:09 8:35. Finally draw a full stop.

The next topic is already behind. Clean up the mood off right!
