Example: CircularArrayRotationOneByOne in Java

// CircularArrayRotationOneByOne
import java.util.Arrays;

// Main class containing the entry point of the program
public class Main {
    public static void main(String[] args) {
        int[] arr = {1, 2, 3, 4, 5};
        int k = 2; // Number of positions to rotate

        System.out.println("Original Array: " + Arrays.toString(arr));

        // Step 1: Handle edge cases for k
        k = k % arr.length;
        if (k < 0) {
            k = k + arr.length;
        }

        // Step 2: Perform k rotations
        for (int i = 0; i < k; i++) {
            int lastElement = arr[arr.length - 1]; // Store the last element

            // Shift all elements from right to left by one position
            for (int j = arr.length - 1; j > 0; j--) {
                arr[j] = arr[j - 1];
            }
            
            arr[0] = lastElement; // Place the stored last element at the beginning
        }

        System.out.println("Rotated Array (One by One): " + Arrays.toString(arr));
    }
