Personal growth
After studying the questions for half a month, I gradually found that the introductory questions have become less and less. After getting in touch with algorithmic questions, the difficulty of common problems is popularization-and popularization/improvement -, and occasionally you can meet popularization +/improvement. In all the basic algorithms, greedy is fairly simple, but today, when choosing a few popular-difficulty questions, it still takes several hours to do a question. In these few hours, the time spent watching other people's problems is far greater than the time spent writing code. There is a big gap between the results I expected, and I feel very uncomfortable. Is this how everyone learns new knowledge? I am not very clear. I am gratified that my growth has been visible in the past half month. I hope that I can continue to work hard. Someone will give pointers and directions. But I know that this is just something you can meet and not ask for. The most important thing is to learn by yourself, keep working hard, maintain a good work and rest, stabilize your mentality, and cheer yourself up, and don't rush for success. If you don't know where your future is, do your current work.
