# x y AR Remarks
where
# = case/run identifier
x = initial x dimension of rectangle (return value)
y = initial y dimension of rectangle (return value)
AR= aspect ratio x / y
N.B. During evaluation, the library always plays optimally.
There are no input files; the initial x, y can be found in rec*.out.
The dialogue between program and library is written to rec*.out.
The file rec*.out is truncated to 1 MB.
Max. score per case: 5 points
