Array Simulation

  You are to simulate the execution of a method
   that manipulates an array of integers.  Consider the following method:

	public static void mystery(int[] list) {
	    for (int i = 0; i < list.length - 1; i++) {
		if (i % 2 == 0) {
		    list[i]++;
		} else {
		    list[i]--;
		}
            }
	}

   In the left-hand column below are specific lists of integers.  You are to
   indicate in the right-hand column what values would be stored in the list
   after method mystery executes if the integer list in the left-hand column
   is passed as a parameter to mystery.

	Original List			Final List
	------------------------------------------------------------

	{6, 3}				____________________________

	{2, 4, 6}			____________________________

	{1, 2, 3, 4}			____________________________

	{2, 2, 2, 2, 2}			____________________________

	{7, 3, 2, 0, 5, 1}		____________________________

1) {6, 3}

2) {2, 4, 6}

3) {1, 2, 3, 4}

4) {2, 2, 2, 2, 2}

5) {7, 3, 2, 0, 5, 1}
