Define reflective codes.
Answer
Reflective codes, such as Gray code, feature mirrored geometric properties where subsequent binary halves reflect the previous halves.
Reflective codes are specialized, unweighted binary encoding schemes engineered such that the upper half of the code sequence is an exact geometric mirror reflection of the lower half (excluding the most significant bit). The Gray code is the most prominent example, designed specifically so that only a single bit changes between any two consecutive sequential values.
