큐파는 선글라스를 하나 꼈다
그 선글라스는 햇빛의 종류에 따라 빛을 투과시키는 양이 달라진다
아시아: 45%를 투과시킴. 55%는 막음
유럽: 77%를 투과시킴. 27%는 막음
아메리카(북,남 포함): 20%를 투과시킴. 80%는 막음
아프리카: 90%를 투과시킴. 10%는 막음
오세아니아: 25%를 투과시킴. 75%는 막음
그리고 큐파는 여행을 가려고 한다
여행은 최소 3개의 대륙은 가야하고, 중복되지는 않는다
이 선글라스는 200%의 빛을 투과시키면 파괴된다고 할때, 마지막 여행지를 나두고 선글라스가 파괴되는 경우의 수와 선글라스가 부셔지지 않고 여행을 하는 경우의 수는?
