2. (10 points) The code in problem #1d represents a sentinel controlled loop that is not working properly. Show two different ways to fix it so it works properly. a. Fix the loop without using a priming read (the original loop is below for you to edit) Scanner stdin = new ScannerSystem.in); final int FLAG = -1; int input = 0; int sum = 0; while (input != FLAG) System.out.println("Enter a number to sum or + FLAG + " to quit"); input = stdin.nextInt0; sum = sum + input
