      Ref: https://prestodb.io/docs/current/functions/array.html and https://prestodb.io/docs/current/functions/map.html

      • element_at(array<E>, index) → E
        Returns element of array at given index. If index > 0, this function provides the same functionality as the SQL-standard subscript operator ([]). If index < 0, element_at accesses elements from the last to the first.
      • element_at(map<K, V>, key) → V
        Returns value for given key, or NULL if the key is not contained in the map.
