이라는 틀을 꺠기 위해 켋이 새로운 전구를 만들었다.
이 전구는 끄거나 킬 수 있지만, 적외선을 발사 할 수도 있다.
적외선을 볼수 있는어떻게 보는거지 켋은 이 전구로 3진법을 나타낼 수 있는 것이다.
켋은 이 전구 세개씩을 묶어 모두 꺼지면 0, 하나가 적외선을 내면 1, 두개가 적외선을 내면 2, 모두 적외선을 내면 3,
한 개가 켜지면 4, 한개가 켜지고 한 개가 적외선을 내면 4, 한 개가 켜지고 나머지가 적외선을 내면 5, 두 개가 켜지면 6,
두 개가 켜지고 한 개가 적외선을 내면 7, 세개 모두 켜지면 8로 9진법을 나타낼 수 있다.
그러나 적외선 따위 볼수 없는 윳은 이 전구가 이진법을 나타내는 것으로밖에 보이지 않는다.
대신, 윳은 전구 두개씩을 묶어 둘 다 꺼져있으면 0, 둘 중 하나가 켜져있으면 1, 두 전구 모두 켜져있으면 2로 생각한다.
켋이 만든전구 18개가 일렬로 서있다.
켋은 이 전구로 474365를 나타내고자 했을 때, 윳이 볼 수 있는 숫자의 최솟값과 최댓값의 합은 얼마인가?
