Bigquery- Declaring an array from list of Integers

I am trying to declare a list of integers as a variable named list_of_ints. My code works, but it seems to be a bit of a workaround:

DECLARE list_of_ints ARRAY <INT64>;
set list_of_ints = (
  SELECT ARRAY_AGG( DISTINCT some_ints)
  FROM (SELECT * FROM UNNEST ([11,22,33]) as some_ints) 
);

I was hoping for something along the lines of

DECLARE list_of_ints ARRAY <INT64>;
set list_of_ints = ARRAY([11,22,33]);

but it seems that this is improper syntax. Is there a way akin to the above attempt to declare an array as a variable in bigquery?

>Solution :

use below

DECLARE list_of_ints ARRAY <INT64>;
SET list_of_ints = [11,22,33];    

OR

DECLARE list_of_ints ARRAY <INT64> DEFAULT [11,22,33]
