Conan is on his skateboard and must disable nine bombs laid out like this
A B C
D E F
G H I
The bombs are about to go off. Conan's mind is racing: "All I need to do is skate past each bomb and pull out the blue wire. The skateboard is fastest when riding it straight and I will lose a lot of time when changing directions. No problem. I can skate past all nine bombs in four straight continuous lines, so I only need to change directions three times." How is Conan going to do it?
