Given an array, A, of N integers, print A's elements in reverse order as a single line of space-separated numbers.

reverse.java

import java.util.Scanner;
public class Reverse{
     public static void main(String[] args) {
         Scanner input = new Scanner(System.in);
        // System.out.println("Enter the size of the array");
         int n = input.nextInt();
         int[] arr = new int[n];
        // System.out.println("Enter array values");
         for(int i=0; i<n; i++){
             arr[i]=input.nextInt();
         }        
        // System.out.println("Enter reversed array");
         for(int i=(arr.length-1); i>=0; --i){
 
             System.out.print(arr[i]+ " ");
         }

  
     }
}
