:)
class Point {
var x: Int
var y: Int
init(x: Int, y: Int) {
self.x = x
self.y = y
}
}
enum Direction {
case left
case right
case up
case down
}
class Robot {
var location: Point
init() {
self.location = Point(x: 0, y: 0)
}
func move(direction: Direction) {
// Enter your code below
switch direction {
case .left: self.location.x -= 1
case .right: self.location.x+=1
case .down: self.location.y -= 1
case .up: self.location.y += 1
}
}
