여러분 모두 한붓 그리기를 알 것이다.
(모르면 선수 개념 배우고 오세요[한붓 그리기])
자 그럼 여기서 "n붓 그리기" 생각하자.
말 그대로 n번만에 선을 떼지 않고 중복되는 선분 없이 그리면 된다.
그렇다면, 두붓 그리기의 조건은 무엇인가?
(한붓 그리기가 홀수점의 개수로 따지듯이, 그런 조건 말이다.)
자 이번엔 3차원으로 가보자...
(이동 중...)
으쌰
자 도착했다. 여기서도 한붓 그리기를 할것이다.
그렇다면, 3차원에서의 한붓그리기는 2차원과의 조건이 다를까?
이를 설명하고,
또한 3차원에서의 한붓그리기가 가능한 모형의 최소 선분개수를 구하시오.
[문제 하나당 해결 하나이며, 풀이는 필수입니다.]
