A helicopter drops two trains, each on a parachute, onto a
straight infinite railway line. There is an undefined
distance between the two trains. Each faces the same
direction, and upon landing, the parachute attached to each
train falls to the ground next to the train and detaches.
Each train has a microchip that controls its motion. The
chips are identical. There is no way for the trains to know
where they are. You need to write the code in the chip to
make the trains bump into each other. Each line of code
takes a single clock cycle to execute.
You can use the following commands (and only these);
MF - moves the train forward
MB - moves the train backward
IF (P) - conditional that's satisfied if the train is next
to a parachute. There is no "then" to this IF statement.

MF
IF (P)
GOTO B
GOTO A
-----
B: MF
GOTO B
Explanation: The first line simply gets them off the
parachutes. You
need to get the trains off their parachutes so the back
train can find
the front train's parachute, creating a special condition
that will
allow
it to break out of the code they both have to follow
initially. They
both loop through A: until the back train finds the front
train's
parachute, at which point it goes to B: and gets stuck in
that loop.
The front
train still hasn't found a parachute, so it keeps in the A loop.
Because each line of code takes a "clock cycle" to execute,
it takes
longer
to execute the A loop than the B loop, therefore the back train
(running
in the B loop) will catch up to the front train.
