    Default Reversed Input

    {
       public static void main(String args[])
       {
           int[] array = StdIn.readAllInts();
           for (int i = 0; i<array.length;i++){
           int temp = array[i];
           array[i] = array[(array.length) - 1 - i];
           array[(array.length) - 1 - i] = temp;
           System.out.print(array[i] + " ");
           }
    }
    }

    What am I doing wrong? My input is {1, 2, 3, 1, 2, 3} and outcome of it is {3, 2, 1, 1, 2, 3}.. How to make to return {3, 2, 1, 3, 2, 1} ?

    What happened when you stepped through this with a debugger, or at least added some print statements, to figure out where the execution of the program differs from what you'd expect?

    Is the objective to reverse the array or just display the data in reverse order? If the latter then just use a reverse loop to print out all values.
