Here are the questions I set today, repeated with the solutions, and a discussion at the bottom. Both puzzles are about binary codes, which are a way of encoding information using only the binary ...

Gray codes, also known as reflected binary codes, offer a clever way to minimize errors when digital signals transition between states. By ensuring that only one bit ...

Do you know how to read binary codes? Pretty impressive if you do, since they’re a computer’s language. Binary coding is a system of counting that boils down to two digits—one (1) and zero (0) that ...
