"In practice, "Gray code" almost always refers to a binary-reflected Gray code (BRGC). However, mathematicians have discovered other kinds of Gray codes. Like BRGCs, each consists of a list of words, where each word differs from the next in only one digit (each word has a Hamming distance of 1 from the next word).

WebMay 25, 2016 · The first algorithm is already as good as it can be: it runs in $ O(1) $ time and works regardless of the number of bits of the two’s complement integer to convert. The second algorithm runs in $ O(\log{n}) $ and is apparently the fastest known algorithm to convert a two’s complement integer to a Gray code. Webgenerating a binary reflected Gray code sequence. In this approach, each sub-problem of the original problem is solved only once in such a way that all 1-bit Gray codes are produced before any 2-bit Gray codes, all 2-bit Gray codes are produced before any 3-bit Gray codes, and so on. The implementation of this approach needs to generate and store
