# THIS CODE IS SUPPOSED TO:
# Gets the radius of a circle from the user,
# and returns the approximation of the circle's area.
# If the radius entered is not valid (i.e., <= 0),
# it returns the string "not a circle".
# Use 3.14 as the value for pi.
#
# It has a bug; try to write test cases to reveal the bug
#
# Do not look at the code.
# You only need a specification to create test cases.
