类名称：Operations
方法名：minus

Operations.minus介绍

[英]Returns a (deterministic) automaton that accepts the intersection of the language of a1 and the complement of the language of a2. As a side-effect, the automata may be determinized, if not already deterministic.

Complexity: quadratic in number of states if a2 already deterministic and exponential in number of a2's states otherwise.
[中]返回一个（确定性）自动机，该自动机接受a1语言与a2语言补码的交集。作为一种副作用，自动机可能是确定的，如果还没有确定的话。
复杂性：如果a2已经确定，则状态数为二次，否则状态数为指数。
