Strobogrammatic numbers are defined as numbers that appear identical when rotated 180°. This property is related to the rotational symmetry of the digits. Valid Digits In the decimal system, only certain digits possess strobogrammatic properties: 0 → 0 1 → 1 8 → 8 6 ↔ 9 Other digits do not form valid numbers when rotated. Therefore, strobogrammatic numbers can only be constructed using these digits. Structure and Rules Single-digit strobogrammatic numbers: 0, 1 and 8. In multi-digit numbers, onl
