题目描述

You are given an array aa with nn distinct integers. Construct an array bb by permuting aa such that for every non-empty subset of indices S=x1,x2,...,xkS={x_{1},x_{2},...,x_{k}} ( 1<=xi<=n1<=x_{i}<=n , 0<k<n ) the sums of elements on that positions in aa and bb are different, i. e.

输入格式

The first line contains one integer nn ( 1<=n<=221<=n<=22 ) — the size of the array.

The second line contains nn space-separated distinct integers a1,a2,...,ana_{1},a_{2},...,a_{n} ( 0<=ai<=1090<=a_{i}<=10^{9} ) — the elements of the array.

输出格式

If there is no such array bb , print -1.

Otherwise in the only line print nn space-separated integers b1,b2,...,bnb_{1},b_{2},...,b_{n} . Note that bb must be a permutation of aa .

If there are multiple answers, print any of them.

说明/提示

An array xx is a permutation of yy , if we can shuffle elements of yy such that it will coincide with xx .

Note that the empty subset and the subset containing all indices are not counted.
