Array Rotation | Block Swap Algorithm

Different Approaches to Perform an Array Rotation Approach 6 - Block swap algorithm for rotate the array to the left or right by 'r' steps, where 'r' is non-negative. Problem: We have an array consisting of Integers ∈ Z of size (n) and a positive integer of rotation count (r) ∈ Z+. We are allowed to shift each of the array's elements by one position. We have to perform left or right rotations in an array. Algorithm Concept: 1. Divide the given array into two sub array A and B where A stores the first ‘r’ elements and B stores the next ‘n-r’ elements. 2. If size of sub array is not equal then perform the block swap b/w A and B, where block size is the size of smaller sub array and then reduce the size of sub array by block size. Repeat this until the size of both sub array is equal. 3. Lastly, perform swap between A and B.
