All records of NOIP2017 PJ and all records of noip2017pj
Preliminary Round
Day-1
Various templates can be used to repeat the algorithm complexity table.
The focus is on a variety of sets. We should just go over number theory and automatic machines.
Review late at night.
Day 0
Relax, play templates, fake real questions, and water number theory.
Hope to pass. Although there is little hope
Go to bed early.
Day 1
Afternoon exam.
Arrive at the test room half an hour in advance to familiarize yourself with the environment.
Open Question.
Thanks to the template we refreshed yesterday, we scored 20 points for the last 27 points...
Multiple choice questionsPas, Pure Mongolia
The program fills in the blanks and deducts 16 points
Estimated 60 points, hope to pass the water
Later, we learned that the Beijing Score Line was 30, which was safe.
Semi-finals
The first universal campaign.
Enter the test room andDALAOThen I took the test.
Open Question.
T1
Actually got a little bit of precision ...... But modified.
The duration is one minute. Change it to LL and Pat.
No error. Leave.
T2
At first glance, we can estimate the complexity so that O (n) can pass through water.
Large simulation + sorting.
It takes 10 minutes.
Card example, find a book with no number of books and then finish the modification.
After 15 minutes, change LL, and beat. No error.
Leave.
T3
No Write, write DFS.
A large example is deleted.
Take violence for 30 minutes.
T4
This is done based on 10% of the data.
Estimated score: 100 + 100 + 30 + 10 = 240
Actual: 100 + 100 + 20 + 10 = 230
