Foreword
As three days of konjac weak market weak area of a weak province, look at your three-year OI time, pronto, but little success.
Fifth grade started to learn in school from scratchAnd sixth grade entry pascal, although the group also participated in the school district the provincial tournament, but in the end I will not even recursive search.
First day into C ++, and soon took part in the noip2017pj(First through the preliminary round I was very happy), T3 search, T4 DP, only fool divided (not say the search qwq), then at 205 minutes (AH scores 210 points) took the second prize.
To the first two days will be a search, but no how to practice dp, noip2018pj T3 had to fight a greedy, T4 see a tree does not want to do, I thought promising first-class 200 points, 224 points folk measured data, the results because T2 is not considered it is placed in the case where m-th bit (one line backward), 182 minutes (AH scores 190 points) and take a second.
Unexamined participated in two noip, I began efforts to brush the winter break two days a lot of dp, team up with classmates to co-workers attended the AH ACM, summer vacation every day to brush the question (although still not much bigwigs brush), from 20 blue title to title Pobai blue, brush a lot of questions, but do not know whether their ability to improve?

2019.10.19 / CSP first round
Exam three years ago to do a preliminary tg roll, I feel okay. The night before the teacher sent Moni Juan, doing the examination paper to explain the video to see coming to 12:00. .
So I No. 19 Fourth confidently into the examination room, tg afternoon pj each morning for two hours, feel the time is not enough. Right right answers out of the examination room to feel cool, especially that there is no path compression volume tg no brain merge disjoint-set, I'd better between complexity O (NlogN) and the hesitation in the worst complexity of O (N ^ 2), eventually chose O (NlogN). . . Then four minutes gone. One last question fairy-like pressure thanks to Mongolia,Five Problems in Four Aspects of Mongolia wrong, 12 points are gone qwq. .
CSP discouraging first-round game: AFO warning. .
Home of the teacher made a reference to the answer, tg 71 points, pj 84.5 points. Do not know can not be too, Huangde a group, it seems I was too water

I can not help but think of a word:
人世间没有一帆风顺的事业，世界历史总是在跌宕起伏的曲折过程中前进的Amway wave
