Create a function that takes an array as an argument and returns true or false depending on whether the average of all elements in the array is a whole number or not.

Examples

isAvgWhole([1, 3]) ➞ true

isAvgWhole([1, 2, 3, 4]) ➞ false

isAvgWhole([1, 5, 6]) ➞ true

isAvgWhole([1, 1, 1]) ➞ true

isAvgWhole([9, 2, 2, 5]) ➞ false
