The properties of  algorithm ?

1. Finiteness(有限性)

    terminates after a finite number of steps

2. Definiteness(明確性)

    rigorously and unambiguously specified

3. Input

    valid inputs are clearly specified

4. Output

    can be proved to produce the correct    

    output given a valid input

5. Effectiveness(有效性，可用紙筆計算)

    basic steps are sufficiently simple and basic
