, and the leaf node object gives real feedback on the message.In strategy mode 3, the context does not have the ability to execute the algorithm, but instead delegates this responsibility to a policy object. Each policy object is responsible for the algorithm that has been encapsulated inside the object. When we issue a "computed" message to these policy objects, they return their respective computed results.1. See chapter 9th, "Command mode", 2. See chapter 10th, "Combination mode" 3. See chapt
