*Here is one effective way of doing this:*
- *First write down the distance you want to go forward in binary, using
the values 1 and 2 to represent the binary digits. This information will
now be available on the starting lampposts.*
- *Now repeat the following:*
- *Trace through the number from right to left, and subtract 1 as you
go.*
- *If the number was 0, then drop the cake right now.*
- *Otherwise trace through the number from left to right, copying
everything one position to the right.*
