题目描述

You are given integer nn . You have to arrange numbers from 11 to 2n2n , using each of them exactly once, on the circle, so that the following condition would be satisfied:

For every nn consecutive numbers on the circle write their sum on the blackboard. Then any two of written on the blackboard 2n2n numbers differ not more than by 11 .

For example, choose n=3n = 3 . On the left you can see an example of a valid arrangement: 1+4+5=101 + 4 + 5 = 10 , 4+5+2=114 + 5 + 2 = 11 , 5+2+3=105 + 2 + 3 = 10 , 2+3+6=112 + 3 + 6 = 11 , 3+6+1=103 + 6 + 1 = 10 , 6+1+4=116 + 1 + 4 = 11 , any two numbers differ by at most 11 . On the right you can see an invalid arrangement: for example, 5+1+6=125 + 1 + 6 = 12 , and 3+2+4=93 + 2 + 4 = 9 , 99 and 1212 differ more than by 11 .

输入格式

The first and the only line contain one integer nn ( 1n1051 \le n \le 10^5 ).

输出格式

If there is no solution, output "NO" in the first line.

If there is a solution, output "YES" in the first line. In the second line output 2n2n numbers — numbers from 11 to 2n2n in the order they will stay in the circle. Each number should appear only once. If there are several solutions, you can output any of them.
