원파는 팔파랑 체스를 두기로 했다.
체스판을 꺼냈는데, 잘 생각해보니 체스 말들을 어디에 뒀는지 기억이 안난다.
여기저기 굴러다니는 것들을 주워보니,
검은 기물은 "킹 하나, 비숍 하나, 나이트 하나"
하얀 기물은 "킹 하나, 퀸 하나,
그리고 맨 앞에 있는 8개짜리 꼬꼬마 한칸씩 가는 기물 하나(이름이 뭔지 아는 분은 댓글 부탁드립니다)"
이때, 검은 기물과 하얀 기물이 서로 공격하지 않는 위치로 배치하는 것이 가능한지와,
그런 배치의 개수, 그리고 그런 배치 중 검은 기물들은 한쪽 반, 하얀 기물들은 반대쪽 반에만 존재하는 배치가 가능한지,
그런 배치의 개수를 구해라.
(기물의 개수가 얼마 되지 않음에 유의하라)
수정 : 맨 앞에 있는 8개짜리 꼬꼬마 한칸씩 가는 기물은 '폰' 이라고 합니다

아마 '폰'일거에요
(여러분이 생각하시는 그 폰 아닙니다)
