Two robots are placed at different points on a straight line of
infinite length. When they are first placed down, they each spray out
some oil to mark their starting points.
You must program each robot to ensure that the robots will eventually
crash into each other. A program can consist of the following four
instructions:
* Go left one space
* Go right one space
* Skip the next instruction if there is oil in my current spot
* Go to a label
[Note that a "label" is a name that refers to a line of your code. For
example, you could label the third line of your program "surveying".
Then, the instruction "goto surveying" would jump to line 3 and start
executing from there on the next cycle.]
A robot will carry out one instruction per second. Both robots need
not have the same program. Note that you won't know ahead of time
which robot is on the left and which is on the right.
