Implement a console-based social networking application (similar to Twitter) satisfying the scenarios below.
Posting: Alice can publish messages to a personal timeline
> Alice -> I love the weather today
> Bob -> Damn! We lost!
> Bob -> Good game though.
Reading: Bob can view Alice's timeline
> Alice
I love the weather today (5 minutes ago)
> Bob
Good game though. (1 minute ago)
Damn! We lost! (2 minutes ago)
Following: Charlie can subscribe to Alice's and Bob's timelines, and view an aggregated list of all subscriptions
> Charlie -> I'm in New York today! Anyone want to have a coffee?
> Charlie follows Alice
> Charlie wall
Charlie - I'm in New York today! Anyone want to have a coffee? (2 seconds ago)
Alice - I love the weather today (5 minutes ago)
> Charlie follows Bob
> Charlie wall
Charlie - I'm in New York today! Anyone wants to have a coffee? (15 seconds ago)
Bob - Good game though. (1 minute ago)
Bob - Damn! We lost! (2 minutes ago)
Alice - I love the weather today (5 minutes ago)
- 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: <user name> -> <message>
reading: <user name>
following: <user name> follows <another user>
wall: <user name> 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.
- Exercise should be done either in Java or C#.
- Provide instructions on how to run the application.
IMPORTANT: Focus on writing the best code you can produce. Do not rush. Take as much time as you need; there is no deadline.
