For a novice like me, I have done a lot of OJs. I would like to recommend to you my current use of OJs. First of all, I use OJs in two parts: solving questions and competing. Writing questions: Jiaozuo No. 1 Middle School OJ (not open to the public), luogu, loj, acwing. You can use these four OJs. Ac = apareciym ce = crucio (co is colloportus) pe = petrificus re = reducto wa = wingardium leviosa mle = muggle. Zhihu, a high-quality Q&A community on the Chinese Internet and an original content platform where creators gather, was officially launched in January 2011 with the brand mission of "allowing people to better share knowledge, experience and insights, and find their own answers." Zhihu relies on seriousness and professionalism.
