Imagine you are developing a software system for a local library. The system includes a feature to categorize books based on their publication year. Some categories of interest are "Vintage Books", which include books published between $1950$ and $1970,$ and "Classic Books", all books before $1950.$ Your task is to write a part of the system that identifies these books.

Given a variable publicationYear, write a statement that prints the message "Vintage Book" to standard output if the value of publicationYear falls within the range from $1950$ to $1970,$ inclusive. If the book was published before $1950,$ print "Classic Book" instead.

Note: You must only write the if statement checking for the conditions and the correct side effect. You can assume the std is available for direct use.
