Hi,

I got this question in my Uber design in specialization round:

Design In memory file system and implement:

Create
Delete
Move

Interviewer was particularly interested in Move method and implementation.
Btw, this system should support Drive,Folder,File types (Drive being on the top hierarchy)

My approach is to create a map of <Path,Entity> and change the path in move. Anyone can tell me of a better approach. I am waiting for my results.
