1. What is the output of the program ? 2. (3 marks) Analyze its time complexity? Justify your answer in detail. The mark is for the justification. A import java.util.ArrayList; public class Complexity { } public static void main(String[] args) { ArrayList numbers = new ArrayList (); } numbers.add (10); numbers.add(20); numbers.add(30); numbers.add(40); } System.out.println("Step A output is: "); Function (numbers); public static void Function(ArrayList arr) { for (int i = 0; i i; j--) { System.out.print (arr.get (j) + ","); } }
