Consider a scenario where you have an Architect who can create architectural plans of buildings but cannot calculate a rough estimation of how much of the raw materials can be consumed in the construction.

Now lets say that a customer wants to save money and does not want to hire an engineer to estimate the amount of raw materials and the cost. The customer requests the architect to create an architectural plan and estimate the cost of the raw materials as well. Create an Adapter so that the architect can estimate the total cost of raw materials using his plan building skills.

The solution for this can be built through the following steps:

$1.$ Create a MakingArchitecturalPlan interface for declaring the make plan function

$2.$ Create a function that defines how to calculate the estimate of the raw materials

$3.$ Create the Architect class which will call and define the MakingarchitecturalPlan interface

$4.$ Create the Cost estimation Adapter which will call the class that estimates the cost of the raw materials

$5.$ Write the client code that will just call the Adapter class and the make plan function
