A digital publishing platform wants to automatically generate unique catalog keys for books in its database.

Table 1 shows some examples of book details.

A catalog key is made up of the:

• bookID
• second letter and the fourth letter of the authorSurname
• first letter of the publisher

For example:

• The catalog key for HAWTHORNE would be B7ATP
• The catalog key for ORWELL would be B12REH

Write a C# program to create this catalog key.

The program should:

• Get the user input for bookID, authorSurname, and publisher
• Create the correct catalog key
• Assign the catalog key to a variable called key

You should use meaningful variable name(s) and C# syntax in your answer.
