DAY591

        Tomorrow exam 《 data structure 》, It looks ok now , There is still some certainty , In many courses , This class is the most attentive in class . Also put 《 Big talk data structure 》 Have a look at , At least there is confidence , however , From the several questions I have done , It seems that the master level is not very good , After all , Whether it's reading , Or listen to class , It's all input , Want to see how you master , You have to pass the test , After all , I don't know how to test the data structure , It seems that the topic sent by the teacher has many conceptual things , It means to deepen the understanding of the concept . We did it together 3 A set of questions , Try to do twoorthree more sets of questions tonight , Understand the wrong again , It's almost there . Today's review , Time is tight , Only the available time can be used , Through the single point breakthrough method, each course was broken one by one . I wish you success tomorrow ！
