ror!(B::BitArray{1}, i::Integer)

ror!(B::BitArray{1}, i::Integer) -> BitArray{1}

Performs a right rotation operation on B.

Examples

1. Perform a right rotation on a BitArray:

   julia> src = BitArray([0, 1, 0, 1, 1]);
   julia> dest = similar(src);
   julia> ror!(dest, src, 2)
   5-element BitArray{1}:
   1
   1
   0
   0
   1

   This example performs a right rotation of src by 2 positions and stores the result in dest.

2. Rotate a BitArray with different length:

   julia> src = BitArray([0, 1, 0, 1, 1, 0, 1]);
   julia> dest = similar(src);
   julia> ror!(dest, src, 4)
   7-element BitArray{1}:
   1
   1
   0
   1
   0
   1
   0

   It demonstrates the right rotation of a BitArray with a different length.

3. Handle edge case with negative rotation:

   julia> src = BitArray([1, 0, 1]);
   julia> dest = similar(src);
   julia> ror!(dest, src, -1)
   3-element BitArray{1}:
   0
   1
   1

   It handles negative rotations correctly and performs a right rotation in the opposite direction.

Common mistake example:

julia> src = BitArray([1, 0, 1]);
julia> dest = similar(src);
julia> ror!(dest, src, 5)
ERROR: BoundsError: attempt to access 3-element BitArray{1} at index [5]

In this example, the rotation index provided is out of bounds for the BitArray. Make sure to provide a valid index within the range of the BitArray to avoid such errors. Always verify that the index is within bounds before using ror!.
