However, the MutableArray could be another direction to consider, just like you did for other functions. I will try it as a follow-up PR. @jayzhan211 I think manually create array for `max(count - array_length, 0)` is just one iteration for the array. The same as `min(array_length, count)`. After creating those two arrays, we can apply `array_concat(array_slice, array_repeat)` easily. -- This is an automated message from the Apache Git Service.
