Python Array Rotation

Question

So I am implementing a block swap algorithm in python.

The algorithm I am following is this:

Initialize A = arr[0..d-1] and B = arr[d..n-1] 1) Do following u

Answer 1

Do you actually need to implement the block swap or are you just looking to rotate the array? In python you can do CW and CWW rotations using

zip(*arr[::-1])

and

zip(*arr)[::-1]
