apcsaArraysSwapMirrorElements


Swap the mirror elements of a given array. Thus, the first and last elements are swapped, the second and second-to-last elements are swapped and so forth. Return the modified array.

HINT
Note that this basically reverses the array. Most people get this problem wrong not by messing up the swaps, but by not thinking through the loop.

apcsaArraysSwapMirrorElements([3, 4]) → [4, 3]
apcsaArraysSwapMirrorElements([5, 8]) → [8, 5]
apcsaArraysSwapMirrorElements([1, 2, 3, 4, 5]) → [5, 4, 3, 2, 1]

...Save, Compile, Run (ctrl-enter)

public int[] apcsaArraysSwapMirrorElements(int[] nums) { }
