Java Program to Print array after it is right rotated K times Last Updated : 25 Jan, 2022 Summarize Comments Improve Suggest changes Share Like Article Like Report Given an Array of size N and a values K, around which we need to right rotate the array. How to quickly print the right rotated array?Examples : Input: Array[] = {1, 3, 5, 7, 9}, K = 2. Output: 7 9 1 3 5 Explanation: After 1st rotation - {9, 1, 3, 5, 7} After 2nd rotation - {7, 9, 1, 3, 5} Input: Array[] = {1, 2, 3, 4, 5}, K = 4. Output: 2 3 4 5 1 Approach: We will first take mod of K by N (K = K % N) because after every N rotations array will become the same as the initial array. Now, we will iterate the array from i = 0 to i = N-1 and check, If i < K, Print rightmost Kth element (a[N + i -K]). Otherwise, Print array after 'K' elements (a[i - K]). Below is the implementation of the above approach. Java // Java Implementation of Right Rotation // of an Array K number of times import java.util.*; import java.lang.*; import java.io.*; class Array_Rotation { // Function to rightRotate array static void RightRotate(int a[], int n, int k) { // If rotation is greater // than size of array k=k%n; for(int i = 0; i < n; i++) { if(i<k) { // Printing rightmost // kth elements System.out.print(a[n + i - k] + " "); } else { // Prints array after // 'k' elements System.out.print(a[i - k] + " "); } } System.out.println(); } // Driver program public static void main(String args[]) { int Array[] = {1, 2, 3, 4, 5}; int N = Array.length; int K = 2; RightRotate(Array, N, K); } } // This code is contributed by M Vamshi Krishna Output: 4 5 1 2 3 Time complexity : O(n) Auxiliary Space : O(1) Please refer complete article on Print array after it is right rotated K times for more details!
