Define a default constructor that initializes the fields numWords $($integer$),$ year $($integer$),$ and author $($string$)$ with the default values $-1,-1,$ and "Incomplete", respectively.

Ex: If the input is $436002004$ Baca, then the output is:

Default values:

Number of words: $-1,$ Year: $-1,$ Author: Incomplete

After mutator methods:

Number of words: $43600,$ Year: $2004,$ Author: Baca

Note: The class's print$()$ method is called before and after the input is passed to the setters.
