바로 전 문제에서 자고 있던 원파를 깨우기 위해,
라임은 아주 기괴한 음악을 틀어 정신을 흔들어 놓으려고 한다.
그러나 음악도 같은 음이나 음절이 반복되면 지루해지기 마련이고, 원파는 깨지 않을 수 있다.
이제 라임은 작곡 프로그램에 들어왔다.
음은 1음 부터 9음 까지 9개의 음이 존재하고,
각 음의 재생시간은 1, 2, 3, 4초중 하나를 선택할 수 있다.
음악의 길이는 10초정도로 하려고 하며,
서로 연결되어 들리는(인접한)음(같은 구간)사이의 음 차이는 4개 이상이어야 하며,
반경 8초내로 같은 음절(음을 2개 이상 연결한 절)이 존재한다면,
원파는 깨지 않고, 오히려 더 잘 수도 있다.
같은 음은 길이에 재생 길이에 상관없이 음만 같으면 된다고 할 때,
라임이 만들 수 있는 기상송의 가짓수는?
