Toy Robot

Toy Robot is a coding challenge commonly used as part of the interviewing process for software development roles. The challenge is to write an application that fits the following requirements:

• The toy robot is placed on a 5x5 table top.
• The toy robot cannot be placed outside these bounds and cannot be moved outside these bounds.
• The user can issue one of five commands to the robot: PLACE X,Y,F; MOVE; LEFT; RIGHT; REPORT.
• PLACE must be the first command used, since the other commands require the robot to be on the table already.
• PLACE X,Y,F will place the robot on the table at the coordinates given, facing in the direction specified (N, S, E or W).
• LEFT will turn the robot 90º to the left.
• RIGHT will turn the robot 90º to the right.
• MOVE will move the robot forward one unit, in whichever direction it is facing.
• REPORT will cause the robot to output its position and direction.
• In my example, I've also implemented an EXIT command to quit the application.

Running the application

1. Install the .NET Core SDK.
2. Clone the solution to your local machine.
3. Using a terminal, navigate to the toy-robot directory.
4. Run the application by typing dotnet run.

Testing the application

1. Install the .NET Core SDK.
2. Clone the solution to your local machine.
3. Using a terminal, navigate to the toy-robot.tests directory.
4. Run the unit tests by typing dotnet test.
