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.
