Yeah, I noticed that too. Treating a byte as eight tally marks misses the point about the combinatorialnature of place settings. It's not 100% wrong, because bit shifting and bit packing are real-world applications used in memory all the time. But these are not the only possible values: 00000001 00000010 00000100 00001000 00010000 00100000 01000000 10000000 It's not incorrect to make a decision to limit one's input to those values, but it is incorrect to presume that binary data can only be recorded that way. Treating those 8 place settings as eight lightbulb circuits that each need an individual test isn't the right mindset for someone performing compiler optimization.
