Edward on Java with Leetcode
Why I’m doing this
I’m not new to Java but haven’t been using it for many years. Now I’d like to brush up my Java skills like a beginner — I assume Java world changes a lot since the time I stopped.
This article will serve as an index of all such articles. My initial thought is to conqure 30 LeetCode algorithm problems within the year of 2023 (the date I wrote this one is 11/24/2023). I may stop if that can give me enough confidence of basic Java knowledge: syntax, common library/class usage and etc. Certainly the activity may continue if I determine otherwise.
An article will be published along with each problem I solve which includes codes, related Java knowledge I learn from solving the problem, a brief or detailed illustration of the algorithm (depending on my understanding of the algorith, if I know it well or feel it straightforwrd, I may make it concise since the key point is to learn the programming language), and a possible Youtube video.
There may be many such activities but I treat this as a learning practice which forces me to learn, summarize, prove (by giving outputs) and reflect (by future inspection). If I cannot elaborate, I may not really understand; if I can note something down, it will be marked deeper in my mind.
