@prologic try converting it as a binary number

@prologic this is something I only learnt from others: the first seven characters (F and Bs) are a binary representation of the row number. The last 3 chars (L and Rs) are a binary representation of the column number.

@prologic RRR gives row seven. Sub R with 1 and you have 111 (which is binary for 7)

@prologic the whole entire "leave only the top halve" part is a little misleading/a complicated way

@prologic don't worry. I completely missed it and only figured it out after it was pointed out by some other code golfers

Yeah I get all that, but you can still do integer arithmetic too. Problem is despite my ParseBoardingpass() func being correct (_or so I think_) with correct test cases, The higestSeatID for my input doesn't quite come out right :/

@prologic try it with this input list and tell me what it outputs.

@lyxal It does not. I switched to using binary and bitwise arithmetic instead. Also solve my input puzzle. Thanks for the tips! I'm not sure what was up with my own implementation before, but I suspect an "off-by-one" which is easy to do if you're not just dealing with the straight up binary that this really is 🤣

I see there's some heated AOC going on here
