Given an array of ints, return a new array of ints containing the first element, the "middle" element and the last element from the input array, in their original order. The "middle" element is defined as the element with index (length / 2). Precondition: the input array will have length >= 3.

HINT
Don't modify the parameter.

apcsaArraysGetFirstMiddleLastElements([3, 4, 9, 2]) → [3, 9, 2]
apcsaArraysGetFirstMiddleLastElements([0, 2, 3]) → [0, 2, 3]
apcsaArraysGetFirstMiddleLastElements([1, 2, 3, 4]) → [1, 3, 4]

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

public int[] apcsaArraysGetFirstMiddleLastElements(int[] arr) { }
