수학동아 - 폴리매스
함께 풀고 싶은 문제
창의력을 기를 수 있는 수학 문제 또는 퍼즐을 내는 곳입니다.
젓가락 게임을 하는 야우심통.
젓가락 게임은 다음과 같은 규칙대로 한다.
1. 순서를 정한다.
2. 각자 두 손에서 손가락을 한 개씩 편다.
3. 자기 순서인 사람은 다음 중 하나를 할 수 있다. 자기 손에 있는 손가락들의 위치를 바꾸거나, 손가락들을 하나로 합하거나 더하거나 빼고, 상대의 손가락을 칠 수 있다.
4. 만약 상대가 나의 손가락을 쳤다면 나의 손가락은 원래 있던 손가락 + 상대가 쳤을 때 상대의 손가락 개가 된다.
5. 누군가 한 명의 손가락이 한 손에 5가 될 때까지 3~4를 반복한다.
자, 젓가락 게임의 필승 조건을 구하시오.
-
1,1에서 순서를 바꿔서 1,1이 되는 것도 가능하나요?
-
그건 안됩니다.
그리고 한 손에만 있을 경우도 바꿀 수 없습니다.
