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.

Assumptions - the track goes North-South
Both trains either face or North or South
Two trains are T1 and T2 and their respective parachutes
are P1 and P2
Algorithm/code-
MF(T1) //Moves T1 in forward direction
MF(T2) //Moves T2 in forward direction
Label:If(T1 at P2) MB(T2)
If(T2 at P1) MB(T1)
GOTO Label
Description - Since both trains are facing same direction
(either N or S) if both start moving forward (say toward N)
at some point of time one train will cross other train's
parachute, at which point we reverse the other train. The
trains are now on a collision course.
