Given an N x N matrix represented as a list of lists, write a function that rotates the matrix by 90 degrees clockwise.
examples:
[[1, 2], rotated -> [[3, 1],
[3, 4]] [4, 2]]
[['a', 'b', 'c'], [['x', 1, 'a'],
[ 1, 2, 3 ], rotated -> ['y', 2, 'b'],
['x', 'y', 'z']] ['z', 3, 'c']]
Try writing two implementations: with and without using zip().
