A Few Design PatternsStrategy, Template, Factory

StrategyLet client and algorithm change independently

Template MethodDefine algorithm skeleton, defer some steps to subclasses

Template MethodDefine algorithm skeleton, defer some steps to subclasses

run(data):format() -> commonrunFFT() -> templatedecode() -> common

Factory MethodDefine an interface to create different algorithmsSeparate object definition, creation and use.
