Write a function that, given the start startNum and end endNum values, return an array containing all the numbers inclusive to that range. See examples below.
inclusiveArray(1, 5) ➞ [1, 2, 3, 4, 5]
inclusiveArray(2, 8) ➞ [2, 3, 4, 5, 6, 7, 8]
inclusiveArray(10, 20) ➞ [10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20]
inclusiveArray(17, 5) ➞ [17]
startNum is greater than endNum, return an array with the higher value. See example #4.
