what would happen if there was no counter though? would the linked list still perform normally?
well javawise theres a class given that does the counter for you.
But if you want to do it manually (like in C, etc.) the data in each structure acts as the counter for the linked list(usually numeric) so more often than not there's a counter for every linked list. but even if there is an event where no sortable data can be found I guess that as long as each item is connected then yes it should still act like a linked list
what exactly are you suppose to do with the linked list?
