题目描述

Polar bears like unique arrays — that is, arrays without repeated elements.

You have got a unique array ss with length nn containing non-negative integers. Since you are good friends with Alice and Bob, you decide to split the array in two. Precisely, you need to construct two arrays aa and bb that are also of length nn , with the following conditions for all ii (1<=i<=n)(1<=i<=n) :

  • ai,bia_{i},b_{i} are non-negative integers;
  • si=ai+bis_{i}=a_{i}+b_{i} .

Ideally, aa and bb should also be unique arrays. However, life in the Arctic is hard and this is not always possible. Fortunately, Alice and Bob are still happy if their arrays are almost unique. We define an array of length nn to be almost unique, if and only if it can be turned into a unique array by removing no more than entries.

For example, the array [1,2,1,3,2][1,2,1,3,2] is almost unique because after removing the first two entries, it becomes [1,3,2][1,3,2] . The array [1,2,1,3,1,2][1,2,1,3,1,2] is not almost unique because we need to remove at least 33 entries to turn it into a unique array.

So, your task is to split the given unique array ss into two almost unique arrays aa and bb .

输入格式

The first line of the input contains integer nn (1<=n<=105)(1<=n<=10^{5}) .

The second line contains nn distinct integers s1,s2,... sns_{1},s_{2},...\ s_{n} (0<=si<=109)(0<=s_{i}<=10^{9}) .

输出格式

If it is possible to make Alice and Bob happy (if you can split the given array), print "YES" (without quotes) in the first line. In the second line, print the array aa . In the third line, print the array bb . There may be more than one solution. Any of them will be accepted.

If it is impossible to split ss into almost unique arrays aa and bb , print "NO" (without quotes) in the first line.

说明/提示

In the sample, we can remove the first two entries from aa and the second entry from bb to make them both unique.
