(3,1,2,1,3,2) 라는 수열은 신기하게도, 1사이에는 숫자 1개가, 2사이에는 숫자 2개가, 3사이에는 숫자 3개가 있다. 이렇게 모든 n에 대해, 2개의 n사이에 n개의 수가 있으면 '랭포드 수열' 이라고 하고, 길이가 n이라고 한다.
위의 예시는 길이가 3인 랭포드 수열이고,
(4,1,3,1,2,4,3,2) 는 길이가 4인 랭포드 수열이다.
1. 길이가 5인 랭포드 수열을 만드시오.
2. 길이가 9인 랭포드 수열을 만드시오
3. 길이가 11인 랭포드 수열을 만드시오
4. 길이가 12인 랭포드 수열을 만드시오
단, 만들수 없다면 불가능하다고 적어라
