GDKOI2021Day5 in mind
overall
Still becomes a double digit
T1
Before the exam, I was looking at the linear inverse element, and then I didn’t look at the inverse element directly... I
made a factorial modulus and exploded on the spot.
Expectation: 0pts
Actual: 0pts
T2
Violent in-depth search
here is a film of a certain dalao that T2 played and checked , but
the score of Subtask 2 was 0. Unfortunately, the score of Subtask 2 was not deceived (the data was so big, and my preprocessing was stuck)
Expectation: 40pts
Actual: 20pts
T3
Violent hitting is very embarrassing, so I get 20pts and I feel good.
Expectation: 0pts
Actual: 20pts
T4
Give the code directly, and let you fight violence
Expectation: 30pts
Actual: 30pts
to sum up
T1 is too BT. T2 is not enough for violence. T3 is metaphysics. The wrong answers are divided into two groups: konjac and dalao1 , dalao2 and dalao3. Then... the konjac group is 20 points, the dalao group is 10 points, and T4 is White give violence points
Expectation: 0+40+0+30=70pts
Actual: 0+20+20+30=70pts
