Right Rotation of an Array
Reversal algorithm for right rotation of an array Given an array, right rotate it by k elements. After K=3 rotation Examples: Input: arr[] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} k = 3 Output: 8 9 10 1 2 3 4 5 6 7 Input: arr[] = {121, 232, 33, 43 ,5} k = 2 Output: 43 5 121 232 33 Note : In the below solution, k is assumed to be smaller than or equal to n. We can easily modify the solutions to handle larger k values by doing k = k % n Algorithm: rotate(arr[], d, n) reverse(arr[], 0, n-1) ; reverse(arr[], 0, d-1); reverse(arr[], d, n-1); // Java program for right rotation of // an array (Reversal Algorithm) import java.io.*; class Test { // Function to reverse arr[] // from index start to end static void reverseArray(int arr[], int start, int end) { while (start < end) { int temp = arr[start]; arr[start] = arr[end]; arr[end] = temp; start++; end--; } } // Function to right rotate // arr[] of size n b...
