2019.11.3 learning summary

It's been nine weeks since the start of school , Summarize and evaluate your training .
In the past nine weeks, I have mainly learned some knowledge points involved in data structure , Understand the principle of these knowledge points , But there is not much in-depth research . Focus on string processing . Through these nine months of reading and doing questions , Basically, I can see the problem and know what knowledge points to use to do it .
Make a list of the good knowledge you already have ：
Tree array 、 Line segment tree 、 Union checking set 、 Dictionary tree 、RMQ、manacher、 Chairman tree 、 Two points 、 Minimum representation 、KMP、 Expand kmp、AC automata 、 The suffix array 、 A monotonous queue 、treap
Those who don't master well are ：
Postfix automaton 、 I haven't read these related questions yet .
And what you haven't learned ： Scapegoat tree 、 Dynamic trees 、 Stretch the tree 、 Tree continuous subdivision
My current state is a good knowledge point , Generally, I know how to do it , But the comprehensive application is still far from satisfactory . Basically, I don't know how to do the problems related to the bad knowledge points .
So the next step is to ensure that the knowledge we have mastered will not be forgotten , Learn to master bad knowledge as soon as possible .
Then I feel like this 9 Weeks of learning is extremely inefficient , There is no previous state , But I feel that my recent state is quite good , There are basically more questions to do and read than before , Then pay more attention to the summary . The awkward thing is that the state is back , In the second half of the week, I have to learn professional courses well , But it doesn't really affect me ACM Learning from , At most, I don't learn in class ACM, Listen to the class well . It seems like getting up late in the past nine weeks , Get up after seven every day . You can get up between six and six thirty , In this way, you can learn before class in the morning . There will always be time , If you can play until one or two points, you can learn .
There was really no sense of crisis before , Relax a lot about yourself . But after watching these regional games , My sense of crisis is becoming stronger and stronger . Through these regional games, I realized the gap between myself and others , I also saw the great progress of others . At the same time, I don't want to leave regret for myself ,ACM You can't do well without working hard , Since you want to make certain achievements, you must strive for them , What others can do is what you can do , The difference lies in who makes more efforts , Not working hard is a waste of time , In the end, I can only regret .
