방문을 열었습니다.
다행히 먼저 온 사람은 잘못 짚었는지 안보입니다.
돌멩이가 보였습니다. 하지만 돌멩이가 하나가 아닙니다.
모든 돌멩이는 한쪽 면은 O.W.L이 써있고 한쪽은 N.E.W.T가 써있습니다.
각 돌멩이는 구분이 안됩니다.
해리가 세어보니 O.W.L이 위로 가 있는 돌멩이는 14개 뿐이었습니다.
N.E.W.T가 위로 가있는것도 세려던 찰나에 방문이 잠기고 어두컴컴해졌습니다.
그리고 어두운 목소리가 들렸습니다.
"돌멩이를 두 묶음으로 나누어라. 각 묶음에 있는 O.W.L이 위로 간 돌의 개수는 같게 해라. 나머지는 어떻든 상관없다."
해리는 어떤 방법으로 돌멩이들을 나눌까요?
