| while !isOnOpenSwitch { | |

| if isOnGem { | |
| collectGem() | |
| } | |
| if isOnClosedSwitch { | |
| toggleSwitch() | |
| } | |
| moveForward() | |
| } | |
| if isBlockedRight || isOnClosedSwitch { | |
| turnLeft() | |
| } | |
| if isBlockedLeft || isOnGem { | |
| turnRight() | |
| } | |
| } |

if isBlockedLeft { turnRight() }
great work
