To solve problems that could not otherwise be addressed.
For intellectual stimulation.
- For me, great algorithms are the poetry of computation
To become a proficient programmer.
- Bad programmers worry about the code.
- Good programmers worry about data structures and their relationships
- Algorithms + Data Structures = Programs.
They may unlock the secrets of life and of the universe.
- Algorithms: a common language for nature, human, and computer
For fun and profit.

Several implementations (quick find, quick union, weighted quick union, and weighted quick union with path compression)

Two fundamental data types for storing collections of objects: the stack and the queue.
