# Prints the lyrics of the song "Old MacDonald" for five different animals.
#
# Algorithm (pseudocode)
# Make a list containing animals and sounds.
# Element n is the animal and n+1 is its sound.
# For each animal/sound pair
# Call song(), passing the animal/sound pair as parameters.
#
# song():
# animal and sound are arguments
# Call firstLast() for first line of song
# Call middleThree() for middle three lines, passing animal and sound
# Call firstLast() for last line of song
#
# firstLast():
# Print "Old MacDonald had a farm, Ee-igh, Ee-igh, Oh!"
#
# middleThree():
# animal and sound are arguments
# Print middle three lines of song with passed animal and sound.
def main():
# Make a list containing animals and sounds.
# Element n is the animal and n+1 is its sound.

# For each animal/sound pair
for idx in range(0, len(animals), 2):
# Call song(), passing the animal/sound pair as parameters.
