Bajtazar 是拜托克现代艺术博物馆的馆长。作为最新展览的一部分，一幅由 Bajtass 创作的巨幅画作被送到了博物馆。博物馆的工作人员立即将这幅画挂在了博物馆最大的墙上。

就在展览开始之前，Bajtazar 决定亲自确认展览是否准备妥当。他刚刚走进展示 Bajtass 作品的展厅，开始仔细地观察这幅画。不幸的是，他无法理解这幅画所传达的寓意。他脑中闪过一个令人不安的念头——也许这幅画本应该以不同的方式悬挂，应该顺时针旋转 90 度！

距离展览开幕时间所剩无几，因此 Bajtazar 不愿请求工作人员重新挂画，除非这确实是绝对必要的。幸运的是，Bajtazar 可以更方便地验证自己的猜想——他手头有这幅画的电子版复制图。请帮助他，写一个程序，将该图像顺时针旋转 90 度。

输入格式

输入的第一行包含两个整数 $n$ 和 $m$（$1 \le n, m \le 1\,000$），表示画作的尺寸。接下来是画作复制图的描述：$n$ 行，每行包含 $m$ 个字符，字符为 '.' 或 '#'。

输出格式

你的程序应输出旋转 90 度后的画作复制图，共 $m$ 行，每行包含 $n$ 个字符，字符为 '.' 或 '#'。
