바로 이전 문제와 바로 이전이전 문제의 확장 문제입니다. 따라서 그림자료를 또 그리지 않습니다.
이전 두 문제들은 이웃한 칸들 중 적어도 3칸이 가득차 있으면 자신도 가득차는 규칙이었습니다.
(1) 적어도 2칸만 차면 자신도 차는 규칙이라면 처음에 어디의 몇 칸을 물로 채워야 최소의 물을 사용할까요?
(2) 적어도 4칸이 차야 자신도 차는 규칙이라면 처음에 어디의 몇 칸을 물로 채워야 최소의 물을 사용할까요?
(3) 물탱크가 육각형이 아닌 사각형이라면 처음에 어디의 몇 칸을 물로 채워야 최소의 물을 사용할까요?
(4) (3)과 마찬가지로 사각형꼴이되, 적어도 2칸만 차면 자신이 찰 경우 처음에 어디의 몇 칸을 물로 채워야 최소의 물을 사용할까요?
(풀이과정은 필수입니다. 1개를 풀면 다시도전과 정/오답 결과를 댓글로 알려드립니다. 2~3개를 풀면 부분해결을 드립니다. 4개 모두 풀어야 해결입니다.)
