Algorithm Declare and initialize an array. Variable n will denote the number of times an array should be rotated toward its right. The array can be right rotated by shifting its elements to a position next to them which can be accomplished by looping through the array in reverse order (loop will start from the length of the array -1 to 0) and perform the operation arr[j] = arr[j-1]. The last element of the array will become the first element of the rotated array Program In Java class RotateRight { public static void main(String[] args) { //Initialize array int [] arr = new int [] {1, 2, 3, 4, 5}; //n determine the number of times an array should be rotated. int n = 3; //Displays original array System.out.println("Original array: "); for (int i = 0; i 0; j--){ //Shift element of array by one arr[j] = arr[j-1]; } //Last element of array will be added to the start of array. arr[0] = last; } System.out.println(); //Displays resulting array after rotation System.out.println("Array after right rotation: "); for(int i = 0; i Output : Original array: 1 2 3 4 5 Array after right rotation: 3 4 5 1 2 Program In C# using System; public class RotateRight { public static void Main() { //Initialize array int [] arr = new int [] {1, 2, 3, 4, 5}; //n determine the number of times an array should be rotated. int n = 3; //Displays original array Console.WriteLine("Original array: "); for (int i = 0; i 0; j--){ //Shift element of array by one arr[j] = arr[j-1]; } //Last element of array will be added to the start of array. arr[0] = last; } Console.WriteLine(); //Displays resulting array after rotation Console.WriteLine("Array after right rotation: "); for(int i = 0; i Original array: 1 2 3 4 5 Array after right rotation: 3 4 5 1 2
