Comparison

An attempt to classify data structures based on feature attributes:

Structure	Stable	Unique	Cells per Node
Bag (multiset)	no	no	1
Set	no	yes	1
List	yes	no	1
Map	no	yes	2

"Stable" means that input order is retained. Other structures such as "linked list" and "stack" cannot easily be defined this way because there are specific operations associated with them.
