Description

Input a black and white image with $n$ rows and $m$ columns, and output it after rotating $90$ degrees clockwise.

Input Format

First line contains two integers $n$ and $m$, representing the number of rows and columns of pixels in the image. $1 \le n \le 100$, $1 \le m \le 100$.
Next $n$ lines, each containing $m$ integers, represent the grayscale value of each pixel in the image. Adjacent integers are separated by a single space, and each element is between $0$ and $255$.

Output Format

Output $m$ lines, each containing $n$ integers, representing the image after rotating $90$ degrees clockwise. Adjacent integers are separated by a single space.
