-get array of constants with n length, array_repeat has the same function as
array_with_constant and is used to be compatible with the hive syntax format
-### example
+## Parameters
-```
-mysql> select array_with_constant(2, "hello"), array_repeat("hello", 2);

-| array_with_constant(2, 'hello') | array_repeat('hello', 2) |
-+---------------------------------+--------------------------+

-mysql> select array_with_constant(3, null), array_repeat(null, 3);
-+------------------------------+-----------------------+
-| array_with_constant(3, NULL) | array_repeat(NULL, 3) |
-+------------------------------+-----------------------+
-| [NULL, NULL, NULL] | [NULL, NULL, NULL] |
-+------------------------------+-----------------------+
-1 row in set (0.01 sec)
