## Usage Examples

These examples are based on the inputs used in Pinot's array function tests.

```sql
SELECT arrayPushFrontInt(intArray, 7) AS updatedArray
FROM myTable
```

Returns `[7, 3, 2, 10, 6, 1, 12]` when `intArray` is `[3, 2, 10, 6, 1, 12]`.

```sql
SELECT arrayPushFrontString(stringArray, 'x') AS updatedArray
FROM myTable
```

Returns `['x', '3', '2', '10', '6', '1', '12']` when `stringArray` is `['3', '2', '10', '6', '1', '12']`.
