ROTATE 90 DEGREES CLOCKWISE HOW TO

There's a blue arrow turned 90 degrees clockwise, and next to it is another 2D array,, , ], whose second column is highlighted in cyan. In the second set, there's a 2D array,, ,], whose second row is highlighted in cyan. There's a blue arrow turned 90 degrees clockwise, and next to it is another 2D array,, ,]. !, ,], and the first row is highlighted in cyan. Put another way, the first row becomes the last column, the second row becomes the middle column, and the last row becomes the first column.
