Data structure notes
Program = Algorithm + Data Structure
An algorithm is a finite set of instructions that, fi followed, accomplishes a particular task. In addition, all algorithms must satisfy the following criteria:
- Input
- Output
- Definiteness
- Finiteness
- Effectiveness
Note:
A program is written in some programming language, and does not have to be finite.
An algorithm can be described by human languages, flow charts, some programming languages, or pseudocode.
引入 time complexities 和 space complexities 的概念。
