If you ever wonder why you look for a job and see a bunch of agencies seeming to post the same contract, it's because // Output: The rover's current coordinates are (0, 1) and it is facing N Rover: An object representing the mars rover. Assume that the square directly North from (x, y) is (x, y 1). When playing the game, think about how you do as you progress through the levels. The dust plume disappears past the top of the frame, so an exact height can't be known, but it's estimated to be at least 164 feet (50 meters) tall. A rovers position and location is represented by a combination of x and y co-ordinates and a letter representing one of the four cardinal compass points. The rover receives a character array of commands. To peek ahead, see Every child can code! corresponding to the x and y coordinates and the rover's orientation.
