Or, we ask ourselves, how many lines of code have been wasted in order to cater to design patterns, how much complexity has been added, and how much training costs have been increased?This is what I said in the comments, o

on the day to see the topic, if you have not tried to summarize the algorithm, if you encounter the data structure has not been seen to accumulate, will someday be useful.Another thing is, I really do not want to brush the game, I feel no meaning, I think the problem solving is two things, one is exercise thinking, one is to make happy on the line. If I look at everything too utilitarian, I feel that it loses its meaning.Come on, by the way, English and Java part is not broken, English will res
