ZJOI2017 Travels __ Summary

Up

I also rarely write a travel notes (after all, not their own provincial election, the right to travel 2333). I feel that Zjoi is a relatively new model, and I have never heard of a lesson in the provincial election. Lecture content is good, zzx search and other people's miscellaneous problem is very good, just not very understand STL have what to say ... Day0

Fly Home (FOG). In the afternoon to Wenzhou, or familiar with the small Wenzhou airport, a door is duck tongue advertising (the opportunity to Tengqiao duck tongue). Go to the Red Sun Hotel to report, and then walk to the hotel. Day1

Morning zzx to talk about the search (and I prepared a project crash. , the previous questions are relatively simple, from dancing link began to have a certain degree of difficulty. The last few Noi were ingenious.
In the afternoon 613 talk about the strange usage of STL, the feeling is not very practical. Then there is the WJZ of the puzzle.
The night is a test machine, there is nothing to say, is to spit the organizer, the car is less arranged a car ... Day2

Morning and afternoon are miscellaneous problems, more difficult, and what atcoder count of the choice to speak (fog).
Evening after dinner back to the hotel. Prepared a search for the lecture, and then recite the board. Day3

Race day, get the title first look. T1 should be the probability problem on the dp,t2 tree-like array on the Cactus, T3 violence can be FFT. Feeling is not very good to do. Look at the part of the T1, about 50 more good to take. Then start the code. The last code of 6k or so, found that do not remember g++ open stack of the compiler command, can not run large data. And then it started to get violent. There were some problems, and it took a long time. Then I found that I dsu on the tree when there was a place to remember ...
Then embarrassed, adjusted 1h did not get out. He went to play the second two questions of violence. The last 30min continued to tune, still did not tune out ... Feeling this is more embarrassing, the final eye only 30~40 points. Knot

In fact T1 I have played a table, but did not pay attention to the rules of the table. T2 's conclusions can also be found in the table. T3 should be more difficult, the level is not enough to solve.
Later still need to pay more attention to, not in the examination room on the dead, to jump out in time. Solving

Not complete, not necessarily continued ...
