Array Rotation | Juggling Algorithm
Different Approaches to Perform an Array Rotation
Approach 4 - Juggling 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:
Left Rotation
Divide the array into M Sets, where M =(is the) GCD (n,r), where ‘n’ is the array size and ‘r’ is the number of rotations and then shift each element of Sets towards left by one position until all elements are shifted.
Right Rotation
Divide the array into M Sets, where M =(is the) GCD (n,r), where ‘n’ is the array size and ‘r’ is the number of rotations and then shift each element of Sets towards right by one position until all elements are shifted.
