수학동아 - 폴리매스
함께 풀고 싶은 문제
창의력을 기를 수 있는 수학 문제 또는 퍼즐을 내는 곳입니다.
한변에 5개의 단위정사각형 초콜릿이 있는 정사각형 모양의 초콜릿이 있다. (즉, 초콜릿에 포함된 단위정사각형 초콜릿은 총 25개이다.) 그리고 맨 왼쪽 하단의 초콜릿 1개에는 치사량의 독약이 들어있다.
선공은 단위정사각형 초콜릿을 1개 골라서 먹는다. 이때, 선공이 고른 단위정사각형 초콜릿의 위치를 기준으로 오른쪽과 위쪽에 있는 것도 모두 선공이 먹는다.
선공이 초콜릿을 먹은 후 후공도 단위정사각형 초콜릿을 1개 골라서 먹는다. 이때, 남은 초콜릿중 후공이 고른 단위정사각형 초콜릿의 위치를 기준으로 오른쪽과 위쪽에 있는 것도 모두 후공이 먹는다.
이것을 반복하여 마지막에 독약이 든 초콜릿을 먹는 사람은 목이 막혀서 죽는다.
다음 물음에 답하여라.
(1) 이 목숨을 건 게임의 필승전략은 누구한테 있으며, 그 전략은 무엇일까?
(2) 한변에 n개의 단위정사각형 초콜릿이 있다고 하자. 이때도 필승전략이 존재할까?
존재한다면 누구에게 존재하며, 그 전략은 무엇일까? 존재하지 않는다면 그 이유는 무엇일까?
(3) 가로에 m개, 세로에 n개의 단위정사각형 초콜릿이 있다면 필승전략이 존재할까?
존재한다면 누구에게 존재하며, 그 전략은 무엇일까? 존재하지 않는다면 그 이유는 무엇일까?
