题目描述

The semester is already ending, so Danil made an effort and decided to visit a lesson on harmony analysis to know how does the professor look like, at least. Danil was very bored on this lesson until the teacher gave the group a simple task: find $4$ vectors in $4$ -dimensional space, such that every coordinate of every vector is $1$ or $-1$ and any two vectors are orthogonal. Just as a reminder, two vectors in $n$ -dimensional space are considered to be orthogonal if and only if their scalar product is equal to zero, that is:

![](/uploads/acgo/image/65c8cc7cee60e9d4_f5e9a65c37fd.jpeg).Danil quickly managed to come up with the solution for this problem and the teacher noticed that the problem can be solved in a more general case for $2^{k}$ vectors in $2^{k}$ -dimensinoal space. When Danil came home, he quickly came up with the solution for this problem. Can you cope with it?

输入格式

The only line of the input contains a single integer $k$ ( $0<=k<=9$ ).

输出格式

Print $2^{k}$ lines consisting of $2^{k}$ characters each. The $j$ -th character of the $i$ -th line must be equal to ' $*$ ' if the $j$ -th coordinate of the $i$ -th vector is equal to $-1$ , and must be equal to ' $+$ ' if it's equal to $+1$ . It's guaranteed that the answer always exists.

If there are many correct answers, print any.
