Misha and Permutations Summation
题意翻译
现在有两个$n$的排列$n$的排列是由0 1 2 ... n − 1
这$n$的数字组成的。对于一个排列$p$,$Order(p)$表示$p$是字典序第$Order(p)$小的排列(从0开始计数)。对于小于 $n!$ 的非负数$x$,$P erm(x)$表示字典序第$x$小的排列。
现在,求两个排列的和。两个排列$p$和$q$的和为$sum =Perm((Order(p) + Order(q))$$%$n!)$
输入格式:
输入文件第一行一个数字 n,含义如题。
接下来两行,每行 n 个用空格隔开的数字,表示两个排列。
输出格式:
输出一行 n 个数字,用空格隔开,表示两个排列的和。
题目描述
Let's define the sum of two permutations $ p $ and $ q $ of numbers $ 0,1,...,(n-1) $ as permutation ![](https://cdn.luogu.com.cn/upload/vjudge_pic/CF501D/9e9fa38d41e951898022055d5e7973b458ae99e6.png), where $ Perm(x) $ is the $ x $ -th lexicographically permutation of numbers $ 0,1,...,(n-1) $ (counting from zero), and $ Ord(p) $ is the number of permutation $ p $ in the lexicographical order.
For example, $ Perm(0)=(0,1,...,n-2,n-1) $ , $ Perm(n!-1)=(n-1,n-2,...,1,0) $
Misha has two permutations, $ p $ and $ q $ . Your task is to find their sum.
Permutation $ a=(a_{0},a_{1},...,a_{n-1}) $ is called to be lexicographically smaller than permutation $ b=(b_{0},b_{1},...,b_{n-1}) $ , if for some $ k $ following conditions hold: $ a_{0}=b_{0},a_{1}=b_{1},...,a_{k-1}=b_{k-1},a_{k}<b_{k} $ .
输入输出格式
输入格式
The first line contains an integer $ n $ ( $ 1<=n<=200000 $ ).
The second line contains $ n $ distinct integers from $ 0 $ to $ n-1 $ , separated by a space, forming permutation $ p $ .
The third line contains $ n $ distinct integers from $ 0 $ to $ n-1 $ , separated by spaces, forming permutation $ q $ .
输出格式
Print $ n $ distinct integers from $ 0 $ to $ n-1 $ , forming the sum of the given permutations. Separate the numbers by spaces.

说明
Permutations of numbers from 0 to 1 in the lexicographical order: $ (0,1),(1,0) $ .
In the first sample $ Ord(p)=0 $ and $ Ord(q)=0 $ , so the answer is ![](https://cdn.luogu.com.cn/upload/vjudge_pic/CF501D/a679b810203bebc832be19db13f34086b96b22f1.png).
In the second sample $ Ord(p)=0 $ and $ Ord(q)=1 $ , so the answer is ![](https://cdn.luogu.com.cn/upload/vjudge_pic/CF501D/555dc3825ed7f9c84abac1e654548c93f3b4f826.png).
Permutations of numbers from 0 to 2 in the lexicographical order: $ (0,1,2),(0,2,1),(1,0,2),(1,2,0),(2,0,1),(2,1,0) $ .
In the third sample $ Ord(p)=3 $ and $ Ord(q)=5 $ , so the answer is ![](https://cdn.luogu.com.cn/upload/vjudge_pic/CF501D/36c19db023b9896b76e9373abb6e4828559b82ac.png).
