That getnewsfeed part is not n*10log10 it is n*10log(n*10) if u had just taken a minheap then polled everytime pq had 10+ elements then it would have been log10

@shahCode one question here:
Do we really need to use these Data structures and these implementation strategies when dealing with real time?

I have another thought that in real time we will be using a database and handling millions of requests. So there would be multiple factors such as network calls, memory, scalability, database type, query optimization etc. So most probably we will rely on writing these logics at the database level not in application code.

Please put your thoughts also. So that our college students or freshers can also have these aspects.
If this video is only for cracking interviews. Then a really good approach.
