Java Program for Program to cyclically rotate an array by one
Given an array, cyclically rotate the array clockwise by one.
Examples:
Input: arr[] = {1, 2, 3, 4, 5}
Output: arr[] = {5, 1, 2, 3, 4}
Recommended: Please solve it on “PRACTICE” first, before moving on to the solution.
Java
import java.util.Arrays; public class Test { static int arr[] = new int[]{1, 2, 3, 4, 5}; // Method for rotation static void rotate() { int x = arr[arr.length-1], i; for (i = arr.length-1; i > 0; i--) arr[i] = arr[i-1]; arr[0] = x; } /* Driver program */ public static void main(String[] args) { System.out.println("Given Array is"); System.out.println(Arrays.toString(arr)); rotate(); System.out.println("Rotated Array is"); System.out.println(Arrays.toString(arr)); } } |
