Rotates the array matrix to the left (or -90 degrees)
A matrix is a two-dimensional array (array of arrays), where all sub-arrays (rows) have the same length. There must be at least two rows. This is an example matrix:
[
[ 1, 1, 1, 1, 1, 1 ],
[ 2, 0, 0, 0, 0, 4 ],
[ 2, 0, 1, 2, 0, 4 ],
[ 2, 0, 3, 4, 0, 4 ],
[ 2, 0, 0, 0, 0, 4 ],
[ 3, 3, 3, 3, 3, 3 ]
]
