But it is there for a long time housebound, all can have the opportunity to incarnate Tony teacher cut bangs push buzz cut hair dye, by the way, manual talent to find something, but the highlight of the embodiment or Chinese cuisine small kitchen god every circle of friends of culinary champions can be heated until the middle of the night. Have a good one

2020

He was trapped in the home preparing for graduation, but in this period of time or on the Internet a lot of lessons, march and April has reported the guitar, vocal music class and so-and-so Java training camp, is essentially a review of the state and is amazed to find using Java write a console based exam system is still quite difficult, may be never too so to manually control the state of the thread. I wrote a HashMap on the public account after realizing that the way of interface oriented document-oriented programming was not deep enough in many placesIt was the first time to look at the source code was very difficult to read, so the article took several days to complete. In general, it’s the data structures and algorithms that make it difficult, because the code itself isn’t written that way, so looking at the library functions and some of the design by Java developers is unfamiliar. Therefore, AT the end of the year, I applied for the algorithm training camp of XXX. After learning and practicing for a period of time, I could really understand those designs and gradually consider the optimization points when doing exercises. In mid-December, I joined the Nuggets community and updated the LeetCode daily series of articles. Thanks that most nuggets articles were recommended to the front page, I really gained more motivation. When I wrote this article, I also just arrived at LV2. A period of deliberate practice of the algorithm although only a month did get substantial growth. Also unexpectedly got the nuggets gift 🎁.

conclusion

In 2020, swallow something like an iron man, but life would be boring if it was smooth sailing. And I’m grateful to someone who gave me a lot of strength when I was like that. In 2021, I will still seize the time to learn, but I won’t be too hard on myself, and I haven’t practiced a complete song for a long time, so I will first set a flag that I can play a few finger tunes perfectly at the end of 2021. Second, The daily series of LeetCode will continue to be updated. Third, I will prepare another two front-end series and Java source series. When the specific content framework is set, I will think about the name haha. Fourth, I will find some friends to write a project in their spare time (I am still thinking about it).

😂 it seems that I am still only suitable for writing technical articles.
