#-----Test Data------------------------------------------------------#
#
# The list in this section contains the data sets you will use to
# test your code. Each of the data sets is a list specifying the
# way in which sheets are pasted onto the billboard:
#
# 1. The name of the sheet, from 'Sheet A' to 'Sheet D'
# 2. The location to paste the sheet, from 'Location 1' to
# 'Location 4'
# 3. The sheet's orientation, either 'Upright' or 'Upside down'
#
# Each data set does not necessarily mention all four sheets.
#
# In addition there is an extra value, either 'X' or 'O' at the
# start of each data set. The purpose of this value will be
# revealed only in Part B of the assignment. You should ignore it
# while completing Part A.
#
# You can create further data sets, but do not change any of the
# given ones below because they will be used to test your submission.
