/**

* Move the bus. Buses only move along the cardinal directions

* (north/south/east/west), not diagonally.

*

* If the bus is stopped (that is, if it was just placed, or if it didn't

* move last time move() was called), then it should attempt to move north.

* If it cannot (no road, or off the map), then it should attempt south,

* then east, then west. If no move is available, it should stay in its

* current position.

*

* If the bus is moving (that is, if it successfully moved the last time

* move() was called), then it should attempt to continue moving in the same

* direction.

*

* If it cannot (no road, or off the map), then it should attempt to turn

* right. For example, if the bus was moving north, but there is no more

* road to the north, it should move east if possible.

*

* If it cannot turn right, it should turn left. If it cannot turn left, it

* should reverse direction (that is, move backward, if possible).

* If it cannot do any of these things, it should stay in its current position.

* @param x

* @param y

please fix the move() method

thank you so much
