class Robot: Machine {
override init() {
super.init()
self.location = Point(x: 0, y: 0)
}
override func move(direction: String) {
switch direction {
case "Up":
location.y = ++location.y
case "Down":
location.y = --location.y
case "Left":
location.x = --location.x
case "Right":
location.x = ++location.x
default:
break
}
}
