How come you get 11 chances to pass when learning binary and only 10 learning BCD?

It doesn’t seem fair.

Grey code. I meant Gray code. Damnit!

I woke up this morning and realised that binary→grey is simply (N EOR (N >> 1)). I don’t know why.

There are 10 types of people when it comes to binary, those that understand it and those that don’t.

Thank you!

Interestingly, there are also 10 types of people when it comes to Gray code, also those that understand it and those that don’t. Despite the fact that it’s 10 OR 11 times more difficult to understand.
