Write a static recursive method public static void invert$($int$[]$ a$)$that$,$ given an array of integers a$,$ inverts the positions of its elements. For example, the call invert$($a$),$ where a is a reference to the array $\{1,2,3,4\},$ should modify the array in such a way that a refers to $\{4,3,2,1\}.$ Test you method and provide the output.
