n = int(input()) arr = list(map(int, input().split())) print(*arr[::-1])

C#

class Solution
{
    public static void Main(string[] args)
    {
        int n = Convert.ToInt32(Console.ReadLine().Trim());

        List<int> arr = Console.ReadLine().TrimEnd().Split(' ').ToList().Select(arrTemp => Convert.ToInt32(arrTemp)).ToList();
    arr.Reverse();
    Console.WriteLine(string.Join(" ",arr));
    }
}

arr = list(map(int, input().rstrip().split()))
print(*arr[::-1], sep= ' ')

solved in JAVA, if this code can be optimized kindly explain

List ar = new ArrayList(500);

        for(int j=arr.size()-1;j>=0;j--)
        {
            ar.add(arr.get(j));
        }

    for(int i:ar)
    {
        System.out.print(i+" ");
    }

what is the issue with this ?

         // Scanner scanner = new Scanner(System.in); 
    // int n = scanner.nextInt();
    // int array1[] = new int[n];
    // for(i=0;i<n;i++){
    //     array1[i] = scanner.nextInt();
    // }
    // for(j=(n-1); j>=0 ; j--){
    //     System.out.println(array1[j]);
    //     for(j=n-1;j>0;j--){
    //         System.out.print(" ");
    //     }
    // }
