# CODE BLOCK ANSWERS ARE BELOW THE PROGRAMS

# PROGRAMS PROVIDED COMPLIMENTS OF THE CLASS
# (Minor editing in spots by Dr. V)
# ATTRIBUTION IS GIVEN ABOVE EACH PROGRAM

# NOTE THAT THERE ARE USUALLY MANY DIFFERENT
# VALID WAYS TO CODE EACH OF THESE TASKS

# 6. by Adam G.
#    Note that we work backwards through the word list!
#    This is so that deleting a word will not affect
#    the remaining words that we have left to check.
