points) The description below explains the Strategy Pattern: In Strategy pattern, a class behavior or its algorithm can be changed at run time. This type of design pattern falls under the set of behavior patterns Its Intent is Define a family of algorithms, encapsulate each one, and make them interchange- able. Strategy lets the algorithm vary independently from the clients that use it Capture the abstraction in an interface, bury implementation details in derived classes You have the following operations . add: a b subtract: a-b divide: a / b, assume a and b are NEVER 0 multiply a b; . power: ab a raise to the power of b. Ex. 24 16 We will make the following assumptions 1 ALL operands are ints 2 ALL return values are ints 3 C 4 Classes do not need any Constructors lasses do not need any data-fields Implement a set of classes and an interface that adheres to the Strategy Pattern
