The application is a simulation of a toy robot moving on a square tabletop,
of dimensions 5
units x 5 units.
There are no other obstructions on the table surface.
The robot is free to roam around the surface of the table, but must be
prevented from falling to
destruction. Any movement that would result in the robot falling from the
table must be prevented, however further valid movement commands
must still be allowed.
Create an application that can read in commands of the following form -
PLACE X,Y,F
MOVE
LEFT
RIGHT
REPORT
PLACE will put the toy robot on the table in position X,Y and facing
NORTH, SOUTH, EAST or
WEST.
The origin 0,0 can be considered to be the SOUTH WEST most corner.
The first valid command to the robot is a PLACE command, after that, any
sequence of
commands may be issued, in any order, including another PLACE
command. The application
should discard all commands in the sequence until a valid PLACE
command has been
executed.

MOVE will move the toy robot one unit forward in the direction it is
currently facing.
LEFT and RIGHT will rotate the robot 90 degrees in the specified direction
without changing
the position of the robot.
REPORT will announce the X,Y and F of the robot. This can be in any form,
but standard
output is sufficient.
A robot that is not on the table can choose the ignore the MOVE, LEFT,
RIGHT and REPORT
commands.
Input can be from a file, or from standard input , as the developer chooses.
Provide test data to exercise the application. (file input commands.txt)
