침대에서 절대 안일어날거예요. 히히.
원파가 365일 누워있는 침대는 그냥 침대가 아니라고 해요.
누우면 잘때는 누운 부분이 안으로 약간 들어가서 자기 좋은 공간을 만들어줘요.
그냥 뒹굴거릴때는 침대가 언덕처럼 한쪽이 볼록해져서, 그냥 침대에서 구르는거 보다 재밌어요.
앉아서 친구들이랑 방방 뛰어 놀때는 침대가 울룩불룩 계속 움직여서 침대에서 잘 떨어질 수 있고 재밌어요.
침대는 3m by 5m 로 엄청 커요.
한 사람 당 x m by y m 공간을 확보하지 못하면, 그 사람은 곧 떨어지게 돼요.
물론, x m by y m 공간은 직사각형 공간이어야 해요.
이의 가로세로가 어떻게 되는지는 무관해요.
x와 y는 한 사람이 떨어질 때마다 값이 바뀌어요.
x는 3 / (서 있는 사람 수) * 2고, y는 25 / (서 있는 사람 수) 이예요.
처음에 친구가 w명 서있었으면, 친구들이 다 떨어지고 나면 몇 명의 친구가 남아 있을까요?
