Same Number of Unique Elements

Write a function that returns true if two arrays have the same number of unique elements, and false otherwise.

To illustrate:

arr1 = [1, 3, 4, 4, 4]
arr2 = [2, 5, 7]

In arr1, the number 4 appears three times, which means it contains three unique elements: [1, 3, 4]. Since arr1 and arr2 both contain the same number of unique elements, this example would return true.

Examples

same([1, 3, 4, 4, 4], [2, 5, 7]) ➞ true

same([9, 8, 7, 6], [4, 4, 3, 1]) ➞ false

same([2], [3, 3, 3, 3, 3]) ➞ true
