Sample tests are broken: a end is missing.

The second example of your description shows that positiv angles have to be rotated to the left (=> neg. to the right - a point for your description?!). So the example for 45 degree looks a little bit strange to me (even for a rotation to the right - "swapped values?"):

[[1, 2, 3, 4],
 [5, 6, 7, 8],
 [9, 10, 11, 12]]

normally should be

[[4],
 [3,8],
 [2,7,12],
 [1,6,11],
 [5,10],
 [9]]

Or where i'm wrong? (i know what you are doing here - but is it really a rotation?)

Interesting kata, but I have a few comments/questions:

• Argument a is apparently meaningless in the counting operation.
• The description refers to infinite possible operations, but only defines operations 0 through 3. What would operations 4+ be?
• The example test has the wrong expected value for 5 to the 13th power.
