| • | Stacks
are considered to be the easiest |
|||||||||
| type
of list to use. |
||||||||||
| • | The
only operations we have on stacks |
|||||||||
| are
to add things to the top of the stack |
||||||||||
| and
to remove things from the top of the |
||||||||||
| stack. |
||||||||||
| • | We
never need to insert, delete, or access |
|||||||||
| data
that is somewhere other than at the |
||||||||||
| top
of the stack. |
