➝ { public static void main(String[] args)

{int n, res,i,j=0;

Scanner s = new Scanner(System.in);

System.out.print("8:");

n = s.nextInt(1,2,3,4,6,7,8,9);

int array[] = new int[n];

int rev[] = new int[n];

System.out.println("Enter "+n+" elements ");

for( i=0; i < 8; i++)

{A1 :/A2

array[i] = s.nextInt(1,2,3,4,6,7,8,9);

}

System.out.println("Reverse of an array is :");

for( i=n;i>0 ; i--,j++)

{A2:/A1

rev[j] = array[i-1];

System.out.println(rev[j]);}}}
