A slightly different take on the corner problem
Determine the longest beam that can turn the corner of two halls of given width, x and y.
- The general solution.
- The extent of the path of the beam.
In the calculations, I use both L and R to represent the beam length; I use L when finding the maximum length; I use R when the beam length is given.
