Thank you for the review.
I will update the example to reflect the correct result.
I will also check the English documentation and other versions for the same inconsistency and update them accordingly.

Just to confirm before updating the examples across languages:
should ARRAY_SIZE(NULL) return NULL or 1 in Doris?
I will align all docs accordingly.

I’ve updated the examples across Chinese, English, and versioned docs to clearly distinguish:
ARRAY_SIZE(NULL) → NULL
arrays containing NULL → element count
Please let me know if any further changes are needed.

This PR fixes the inconsistency between the description and example
for ARRAY_SIZE(NULL) reported in #3073.
I did not receive a response on the issue, so I aligned the description
with the example behavior. Please let me know if a different wording
is preferred.
