Lists
ADT (brief intro):
Abstract Data Type
A DESCRIPTION of a data type
The data type can be anything: lists, sets, trees, stacks, etc.
What we want to do at the ADT level is describe what it is and
Sorting
Taking an arbitrary permutation of n items and
rearranging them into total order
Sorting is, without doubt, the most fundamental
algorithmic problem
Supposedly, 25% of all CPU cycles are spent
Tree (new ADT)
Terminology:
A tree is a collection of elements (nodes)
Each node may have 0 or more successors (called children)
How many does a list have?
Each node has exactly one predecessor (calle
