Worklog Time Spent: 10m
Work Description: zabetak commented on PR #4223:
URL: https://github.com/apache/hive/pull/4223#issuecomment-1505163499
Also regarding the empty ARRAY<INT> representation should it be the A1 or A1?
**A1**
```
TOK_SELEXPR
TOK_FUNCTION
array
TOK_FUNCTION
TOK_INT
TOK_NULL
```
**A2**
```
TOK_SELEXPR
TOK_FUNCTION
array
TOK_FUNCTION
TOK_INT
TOK_NULL
TOK_FUNCTION
TOK_INT
TOK_NULL
```
I see that **A2** is mentioned in the description of the PR but I would
expect that it was **A1**.
