1920 Special Sem1 Q9 Asychronous Programming

I am not sure about how to do this question. Are we supposed to covert both u and p to completable future?

[Brandon-Chiu]

I converted both u & p to CompletableFuture as usernameExists and isValidPassword could take a long time to run which might be the issue here.
Do take note that as the question wants us to return an object of type CompletableFuture, all the return statements need to be edited such that a CompletableFuture object is returned instead.

Hi, there is more discussion at #298!

Hello! This was my code for this part, but I am not 100% sure if it is right or not. The part where u and p is placed into CompletableFuture should be right I think.
