So, what is Discrete Structures (DS)?
These are the abstract mathematical structures used to represent discrete objects and relationships between those objects.
Why is DS important?
These structures form the conceptual basis for many of the data structures that we use as programmers. To use DS as abstract models for use in solving problems and developing algorithms.
How do we apply DS?
Functions, relations, and sets,
Basics of counting,
Graphs and trees,
