# Robot Simulator
|
|
|
|
Write a robot simulator.
|
|
|
|
A robot factory's test facility needs a program to verify robot movements.
|
|
|
|
The robots have three possible movements:
|
|
|
|
- turn right
|
|
- turn left
|
|
- advance
|
|
|
|
Robots are placed on a hypothetical infinite grid, facing a particular
|
|
direction (north, east, south, or west) at a set of {x,y} coordinates,
|
|
e.g., {3,8}, with coordinates increasing to the north and east.
|
|
|
|
The robot then receives a number of instructions, at which point the
|
|
testing facility verifies the robot's new position, and in which
|
|
direction it is pointing.
|
|
|
|
- The letter-string "RAALAL" means:
|
|
- Turn right
|
|
- Advance twice
|
|
- Turn left
|
|
- Advance once
|
|
- Turn left yet again
|
|
- Say a robot starts at {7, 3} facing north. Then running this stream
|
|
of instructions should leave it at {9, 4} facing west.
