+Returns `True` if two lists contain the same elements regardless of order, `False` otherwise.
+
+Use `set()` on combination of both lists to find the unique values.
+Iterate over them with a `for` loop comparing the `count()` of each unique value in each array.
+Return `False` if the counts do not match for any element, `True` otherwise.
