2019.7.22 exam reflection

Gradually peace of mind. . .

T2 is one up found the original title, flattered started to play N 3 violent, pro-test can A can not N 2 is too hard tune

Then off to a great come back after being told to replace T2

T1 start saw about 15 minutes there, died on exgcd but I guess I remember the board also pushed out, trained, trained, trained,

Then the card for a while to see what T2,30 points did not want to, then treat it as a math point of view, pushing for a formula, the number of combinations should be steady.

After completion code to see T3, emmmm. . Probably played more than one hour of large simulation.

Went back to look at T2, the small sample% hand make life difficult for the re-launch formula that seems to have relations with several Cartland, and found that there are duplicate inclusion and exclusion need to manually hack off yourself.

Then calm face death.

 

How should I say, the problem exposed is not fully consider the issue, such as special judge T1, T3, for example, a large simulation.

After T1 take a look, feel special if calm is to play the whole sentence and then get 60 to 80 minutes.

T3 pity, without taking into account back to the beginning and start the reverse situation really is a pit sample

T2, then the number of combinations and ultimately a relationship, but it does not get 30 minutes in the case of forgery of N 3 violence.

 

Exam, face possible correct what they want, and not too much doubt, although I think I did not have time to prove

In no rush to play a certain grasp of the situation, but not a prudent step by step get points, this is a very wrong approach.

It stands to reason that we should forget or do not stand a flag stand up
