Details
● The application must use the console for input and output.
● Users submit commands to the application. There are four commands. “posting”, “reading”, etc.
are not part of the commands; commands always start with the user’s name.
○ posting: ->
○ reading:
○ following: follows
○ wall: wall
● Don't worry about handling any exceptions or invalid commands. Assume that the user will
always type the correct commands. Just focus on the sunny day scenarios.
● Don’t bother making it work over a network or across processes. It can all be done in memory,
assuming that users will all use the same terminal.
● Non-existing users should be created as they post their first message. Application should not start
with a pre-defined list of users.
● Use whichever language, libraries, frameworks and tools you like.
● Provide instructions on how to run the application.
