Write a Java method int[] easyAs123(int[] nums) that takes an array of integers and returns an array that contains exactly the same numbers as the given array, but rearranged so that every 1 and 2 is immediately followed by a 3, in the order of appearance, as in the test cases below. Specifically, 1) In the input array, every 1 is always immediately followed by a 2. 2) However, even though every 2 is immediately followed by a number, not every 2 is immediately followed by a 3. 3) Do not move the 1 and 2's, but every other number may move to swap place with a 3. 4) The input array contains the same number of 1's, 2's and 3's.
