Hint
Who is in last place?
Answer
This cannot happen, you cannot overtake the person who is in last place, as there is no-one behind them!
Ovetaking = passing someone who is ahead on the same lap, this is a change of position, e.g. 4th moves up to 3rd.
Lapping = passing someone who is a full lap behind, this isn't a change of position, e.g. 4th stays 4th.
Puzzle 18
This BrainBashers safe has a rather unusual control panel.
In order to open the safe, you have to press every single square once only, in the correct sequence, ending on the square marked E.
Each square indicates which square to press next, for example, 2U means move up 2 squares and 3R means move right 3 squares.
Can you determine which square you must start with?
