An artist's discography includes several albums. Each album includes several songs. We want to model the Discography, Album and Song classes as follows • a discography has a single artist attribute and a total_time method that returns the total minutes corresponding to the artist's entire discography • an album has a single name attribute and a total_time method that returns the total minutes for the songs on the album a song has two attributes: title and duration and a duration method that returns the duration in minutes of the song we want to take advantage of the composite pattern so that the duration method delivers the total number of minutes of a song, album or the entire discography of the artist depending on the object in question a) Draw a UML class diagram showing the solution
