It works when I put elements in the @nums but I am just confused on the unknown length part.
ofcourse, the array  @nums = () is empty.
unknown length doesn't mean EMPTY array, does it?

Infact, your code will die with an error message, illegal division by zero at ... because the variable $size will be 0 since the array is empty.

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
