Question 4
To remember how to reach places along wooden paths, the beavers record their turns (the choices at three-way junctions) throughout a journey. They record a right turn as R (right) and a left turn as L (left).
For example, on the paths below, the route from S to the butterfly is recorded as: S R L R L.
One fine day, a beaver sets out from home to enjoy the scenery and stops at the position shown below. How many R characters and how many L characters are in the record of this journey?
