	# a way to check if your code is working: 

	# printf "\x00\x00\x01\x01\x00" | python3 program.py | hexdump

	# it will print out what it would move (in the same format of 00 = defect, 01 = coop) against defect defect coop coop defect
	# if your program prints out anything but \x00 or \x01 it is invalid.

	# example correct tit for tat output
	# $ printf "\x00\x00\x01\x01" | python3 example.py | hexdump
