# In Haskell, you write a function like this:
#   f :: a -> b
# which reads as "f is a function from type a to b"
#
# Function composition allows you to chain functions together,
# building more powerful and complex composite functions from
# simpler component functions.
#
# OOP does not have a similar mechanism. Composition in OOP seems
# to mostly be limited to aggregation and delegation, neither of

Queen Attack

In the game of chess, a queen can attack pieces which are on the same row, column, or diagonal.

A chessboard can be represented by an 8 by 8 array.

Write a program that positions two queens on a chess board and indicates whether or not they are positioned so that they can attack each other.

Chapter 1 - Object Oriented Design

The purpose of design is to allow you to do design later, and it's primary goal is to reduce the cost of change.

SOLID Design:

• Single Responsibility Principle: a class should have only a single responsibility
• Open-Closed Principle: Software entities should be open for extension, but closed for modification (inherit instead of modifying existing classes).
• Liskov Substitution: Objects in a program should be replaceable with instances of their subtypes without altering the correctness of that program.
• Interface Segregation: Many client-specific interfaces are better than one general-purpose interface.
