It's probably for you to define.

If you scroll down a bit more you'll see they have a constructor for a SkipList object that sets MAXLVL

glass ridge If you scroll down a bit more you'll see they have a constructor for a SkipList ...

but MAXLVL is still a variable and as far as I understand, normal arrays cannot be created using variable integers. You would have to use a dynamic array

#

but its fine, i figured out my skiplist
