Matrix Rotation: 90-Degree Clockwise

You are given a matrix with dimensions \( n \times m \). Your task is to rotate the matrix by 90° clockwise. In other words, the element originally at position \( (i,j) \) in the matrix will move to position \( (j, n-1-i) \) in the rotated matrix. For example, given a 3x3 matrix:

1 2 3
4 5 6
7 8 9

After rotation, it becomes:

7 4 1
8 5 2
9 6 3

Note that the rotated matrix will have dimensions \( m \times n \). Use standard input (stdin) to read the input and standard output (stdout) to print the resulting rotated matrix.

inputFormat

The first line of input contains two integers, \( n \) and \( m \), representing the number of rows and columns of the matrix respectively. The following \( n \) lines each contain \( m \) space-separated integers representing the matrix elements.

outputFormat

Output the rotated matrix. Each of the \( m \) rows should contain \( n \) space-separated integers representing the rotated matrix.
