非升序列是指一个序列 a1 a2 a3 … 满足 a1 >= a2 >= a3 …

非降序列是指一个序列 b1 b2 b3 … 满足 b1 <= b2 <= b3 ...

-Combined list, given a non-l sequence and a non-drop sequence, asked that it be merged into a sequence of non-liters and output. Non-L sequence is a sequence a1 a2 a3 ... meet a1>　= a2>　= a3 ... nondecreasing sequence is a sequence b1 b2 b3 ... meet b1 < = b2 < = b3 ...
