) 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,assumeaandbareNEVER0.

multiply : a ? b;

power: ab ,araisetothepowerofb. Ex. 24 =16.

We will make the following assumptions:

1 ALL operands are ints.

2 ALL return values are ints.

3 Classes do not need any data-fields

4 Classes do not need any Constructors

Implement a set of classes and an interface that adheres to the Strategy Pattern.
